American Idol

7:40 PM PDT -- Cops tell us Gracin is being held on a 5150 psychiatric hold. We're told he drove himself to a hospital, with a police escort, after they pulled him over. He's been cooperative, has spoken to his family ... and is being evaluated by doctors now.

5:33 PM PDT -- We're told cops intercepted Gracin on his way home and all they'll say is, "He's safe."

'American Idol' Season 2 finalist Josh Gracin had neighbors and police racing to his door ... after posting what looked like a suicide note in the wake of marital problems.

We're told cops responded to the former Marine's home in Spring Hill, TN -- where he lives with his wife and 4 kids -- for a welfare check after a family member saw an ominous Facebook post:

"I've loved her for 17 years ... I made mistakes ... I admitted them, told her the truth and she turned her back on me when I needed her help the most."

He continued, "Please remember me as someone who gave his all in his music ... Pray for my family as they carry on in this world without me. Goodbye."

Cops rushed to his house -- his wife was there but he wasn't. Law enforcement sources tell us police got in touch with him by phone, put him on with his wife, and he told her he was coming home.

Cops are staying at the home until Josh arrives.

Story developing ...

Katharine McPhee's hubby claims his estranged wife is a cheater and a liar.

Nick Cokas has filed new divorce docs -- obtained by TMZ -- which squarely contradict Katharine's version of the timeline of their separation ... which is relevant because of the photos showing her making out with "Smash" director Michael Morris.

Katharine claimed in her divorce docs they separated in March, 2013 -- months before pics surfaced in October showing Katharine and Michael sucking face.

But Nick begs to differ, claiming the separation was actually in May, 2014 ... long after Katharine hooked up with Michael.

Nick has some pretty powerful evidence to back up his version, including emails and texts about their relationship. Family sources say Nick can show he and Katharine were in marriage counseling AFTER the pictures surfaced.

The separation date is important because it determines when Katharine's money becomes hers alone.

Former "American Idol" contestant Michael Johns may have been dead for more than an hour before he was discovered ... according to the friend who found him.

TMZ has obtained the dramatic 911 call. Michael's friend tearfully tells the dispatcher he had left Johns 2 hours before and he seemed ok, but when he returned Michael was motionless ... and not breathing.

The friend tells the dispatcher he fears Michael is dead and says Michael was cold to the touch and it appeared rigor mortis had set in.

You hear the friend breathlessly perform CPR ... to no avail.

The autopsy on former "American Idol" contestant Michael Johns has been completed, but the medical staff at the Orange County Coroner's Office is deferring the cause of death ... pending toxicology results.

TMZ first reported ... Johns had sprained his ankle and the swelling spread up to his knee. He went to the doctor Thursday ... the day before he died. We're told he was in great pain.

Law enforcement sources tell TMZ ... the police were informed Johns had engaged in heavy alcohol use at some point prior to his death. And we're told he was a heavy drinker.

One law enforcement source tells us ... it would be fairly routine if the doctor who saw Johns on Thursday prescribed pain meds.

If there was a blood clot, it would appear it was not clearly the cause of death ... or else the case would be closed. The fact that toxicology tests are being performed suggests the Coroner wants to know if alcohol and/or drugs played a part in Johns' death.

Michael Johns had been drinking heavily at some point before he died Friday ... TMZ has learned.

As TMZ previously reported ... the "American Idol" Season 7 contestant died Friday at a friend's home in Orange County. TMZ reported there was evidence of a blood clot. We're told Johns had sprained his ankle and it swelled to his knee. He sought medical attention the day before he died.

Law enforcement sources tell us ... police were told Johns had been heavily drinking. It's uncertain what the time frame was ... as in how close to his death he was boozing.

We don't know if Johns had received pain meds from the doctor. Obviously, there would be concerns about mixing alcohol with pain meds.

We're told when EMTs got on scene Johns was in full cardiac arrest and could not be revived.

An autopsy is being performed.

5:00 PM PST -- Sources close to Michael Johns tell us he went to a doctor on Thursday to check out the pain he had been feeling in his ankle ... the swelling and bruising had made their way up to his leg.

Doctors didn't find any problems however -- so they cleared him to go home.

We're told the next afternoon at his friends apartment ... Johns' body was found on the couch unresponsive. When paramedics arrived, he was already dead.

"American Idol" finalist Michael Johns died Friday at the age of 35.

The singer's death was caused by a blood clot in his ankle ... sources tell us he had twisted his ankle earlier and was in a great amount of pain.

People close to Johns tell us ... it appears the ankle injury triggered the clot. We're told he died in his sleep.

The singer placed 8th in Season 7 (2008) and following his exit from the show he continued to record music. He recorded an album -- "Hold Back My Heart" in 2009.

He'd also done a tremendous amount of charity work with former executive producer Nigel Lythgoe.

Lythgoe tells TMZ, "He was a great talent and dear friend. My boys and I are devastated."

Johns was married to Stacey Vuduris. They married in 2007.

The singer's family says, "Our family is devastated by the passing of our beloved Michael, a wonderful husband, son, brother, uncle, and friend. We appreciate the outpouring of love and support we have received from all corners of the globe."

The last time we shot Michael he was in great spirits.

Soon-to-be divorcée Katharine McPhee did a little advertising on the beach in Cabo this weekend ... showing off her tan-lined body less than two weeks after pulling the plug on her marriage.

As TMZ first reported, McPhee said in her divorce docs she and hubby Nicholas Cokas were separated for seven months before she was spotted locking lips with "Smash" director Michael Morris.

Katharine McPhee insists she's no cheating skank -- claiming she was SEPARATED from her husband last year when she publicly made out with another man.

TMZ has obtained McPhee's divorce docs -- she lists her date of separation from husband Nicholas Cokas as March 15, 2013 ... more than 7 months before she openly locked lips with married "Smash" director Michael Morris.

As we reported, McPhee filed for divorce from Cokas last week. She cites irreconcilable differences in the docs.

Also interesting ... according to the docs, McPhee wants to keep all the money she made post-separation ... which might explain why she picked such an early separation date.

McPhee and Cokas briefly attempted a reconciliation in March ... but that just didn't work out.

Ryan Seacrest finally got a chance to show off his singing chops on "American Idol," but sadly the world discovered ... he doesn't have any.

Even sadder -- the fact poor Richard Marx was 'Right There Waiting' ... for Ryan to stop butchering his song.

Katharine McPhee has finally pulled the plug on her marriage from the man she publicly cheated on.

Katherine's rep released a statement confirming the divorce, saying, "After six years of marriage, and having been separated for the past year, [Katharine] has filed for a dissolution of marriage from Nick Cokas."

The rep added, "The two have an amicable relationship and will remain friends."

"Amicable" is surprising ... considering 30-year-old McPhee humiliated 49-year-old Cokas last year by publicly making out with "Smash" director Michael Morris ... who also happens to be married.

As we reported, McPhee and Cokas tried reconciling earlier this Spring, but it just wasn't in the cards. We're told McPhee ultimately decided she just didn't want to be married anymore.

Ryan Seacrest finally showed off his singing chops for the world to see ... and the world wishes he hadn't done that.

Seacrest, always on top of the latest musical trends, belted out the classic 1989 Richard Marx song "Right Here Waiting" ... and "American Idol" even unearthed Marx to sing it with him!

Say what you will about Ryan's singing -- and it was awful -- he didn't hide behind any audio gimmicks ... he straight up sang his heart out.

"Twilight" star Nikki Reed has filed for divorce from former "American Idol" contestant Paul McDonald ... TMZ has learned.

In the divorce docs, obtained by TMZ, Reed cites irreconcilable differences. She's also asking the court to deny McDonald spousal support. It was the first marriage for both. The couple had no kids together.

Reed and McDonald announced they were splitting back in March ... and revealed they'd already been living apart for 6 months.

Interestingly, even though several reports had the couple getting married in October 2011 -- in the docs their marriage date is July 14, 2011.

Despite the split, Nikki and Paul have continued working on an album together. Not weird at all.

Jennifer Lopez and her mother were cruising through Manhattan when it happened -- our camera guy got the magical shot that proves Jenny from the block ... is also a chip off the ole one.

And Mama Lopez has all the proof (and junk) we need (in her trunk).

Jennifer Lopez and her mother were big hits walking the streets of Manhattan yesterday, and if you didn't know they were related ... a quick pan down of our camera revealed the family resemblance.

J. Lo and her mother, Guadalupe were shopping on Madison Ave. where they encountered a bunch of fans ... including one woman who joked she was happier to meet mom than J. Lo.

Jenny does talk to us about where she used to get her hair did -- but, honestly, it was hard to focus due to the view of mother and daughter butt ... and their shared DNA.

1:26 P.M. PDT -- Scotty is now talking about the robbery. He just Tweeted, "Yes, it was definitely a very scary night. Luckily, my friends and I are safe and the Raleigh PD is on the case." Scotty also thanked police for their quick response and said, "I will share more when the time is right, but as of now we do not want to do or say anything that could hinder the investigation."

Country singing former "American Idol" star Scotty McCreery was a victim of a home invasion robbery Monday morning.

The Season 10 "Idol" winner was visiting friends at an apartment around 2AM near the North Carolina State University campus -- where McCreery is a student -- when the incident occurred.

According to law enforcement, 3 gunmen barged into the unit -- while McCreery and his friends were inside -- and made off with cash, wallets, and other property, including valuable electronics.

We also obtained the 911 call which includes a bunch of other details -- the caller says the intruders were black, dressed in black sweat pants and gray hoodies. The caller says he was in another room when they barged in, but he could hear them say, "Everyone on the floor. Give us everything you've got."

No one was injured.

The 911 call made after Scotty McCreery and a few friends were robbed at gun point was not made by the teacher from Charlie Brown ... it just sounds like it.

TMZ has obtained the 911 call made early Monday morning after three gunmen broke into an apartment near North Carolina State University and made off with cash, wallets, and other property, including valuable electronics.

It's hard to say whether the "American Idol" champ is the one who placed the 911 call ... because North Carolina state law calls for the voices to be distorted on the tape.
