Good Morning America

BRAVO! Lindsay Lohan's such a brilliant actress ... she nearly convinced the world today that she didn't know about her newly-announced 17-year-old half-sister -- claiming, "I don't pay attention to any of that."

Of course, the news was everywhere yesterday after TMZ broke the story -- Lindsay's dad Michael Lohan took a paternity test for a 17-year-old girl named Ashley ... and the results came back positive.

But today on "Good Morning America" -- where Lindsay was trying to promote her new movie "Liz & Dick" -- she had the audacity to say, "I didn't even hear that."

There was no delay, no bleep and cutting away from Tom Hanks this morning on "Good Morning America" as he dropped an F-bomb live on the air ... just seconds before predicting he would.

"GMA" host Elizabeth Vargas asked Hanks to speak in the same accent he does in his new movie, "Cloud Atlas." Hanks said that would be tricky since it's mostly swear words ... and then he proceeded to try ... and cursed anyway!

Hanks apologized profusely, as did Vargas, and Hanks made another (probably) accurate prediction ... that his next appearance on the show will come with a seven second delay.

Clint Eastwood says he doesn't really give a crap about the people who ripped his impromptu "chair" speech at the Republican National Convention ... saying he was just expressing his feelings.

Clint appeared on "Good Morning America" this morning ... and the 82-year-old explained one of the reasons he didn't want to give a traditional speech off a teleprompter that night is because "I didn't have my glasses with me ... so I wouldn't have been able to read it."

Instead, he explained ... "So then I’m just sitting there and the guy says, ‘You wanna sit down?’ and I said ‘No, but put that [chair] next to the podium will ya.'"

And a legend was born.

When he was told that Obama is still a fan of his, Clint said, "Well, that's his bad judgment."

As for the criticism Clint has received since the speech ... Clint says, "There is something about the aging process that makes you give a crap less."

Matt Lauer does NOT believe Al Roker is trying to sabotage the "Today" show ... despite his crazy antics ... telling TMZ that any talk of a riff between Al and the show is nothing more than a "rumor."

Matt was on his way home from the gym in NYC yesterday when we asked about all of the drama with the "Today" show ... including the fact that rival "Good Morning America" has TAKEN OVER as ratings leader in the morning news war.

"We feel the heat every day," Lauer says ... "but we have for the last 20 years that I've been there."

"We're just trying to do the best show we can do every single day ... and I think we're doing a good job right now ... and I think the cycle will reverse."

It's almost too much for anyone to bear ... Now we know why "Good Morning America" anchor Robin Roberts left a day before her scheduled medical leave -- her mother died Thursday.

Roberts -- who will be taking several months off to undergo treatment -- including a bone marrow transplant -- for a rare blood disorder -- flew to Mississippi Thursday to see her 88-year-old mother, Lucimarian Tolliver Roberts, before she passed away.

Robin Roberts just announced ... she will begin her medical leave from "Good Morning America" TODAY ... one day ahead of schedule ... after "some things happened at home."

Roberts -- who was recently diagnosed with MDS -- had originally planned to stay through tomorrow before leaving the show to prepare for her bone marrow transplant.

But this morning, an emotional Roberts explained, "I had planned to let tomorrow be the last day ... and then some things happened at home and I wanna take care of that before I begin my treatment next week."

Country star Martina McBride performed a song for Robin ... and Roberts, with a smile on her face, tearfully sang along.

Robin Roberts was forced to back out of the first interview with Chad Johnson's estranged wife Evelyn Lozada since he allegedly attacked her earlier this month -- and TMZ has learned, it's due to Robin's health crisis.

Sources tell us ... Evelyn agreed to sit down with Robin on "Good Morning America" to discuss the Aug. 11 domestic violence incident -- because she feels Roberts has tremendous integrity as a reporter.

The interview was set for this week, but hit a snag when Lozada asked Robin to tape the segment at her hotel ... since Evelyn wanted a private setting for such a serious conversation.

We're told Roberts couldn't make that happen because she would have to miss a treatment session for her blood disorder ... myelodysplastic syndrome (MDS).

As we reported, Roberts is scheduled to start a leave of absence this Friday to receive a bone marrow transplant.

Robin Roberts will begin her medical leave from "Good Morning America" on Friday ... so she can undergo bone marrow transplant surgery.

Earlier this year, Roberts announced she was diagnosed with myelodysplastic syndrome (MDS) ... a disease that attacks the blood and bone marrow.

Roberts says her sister is the bone marrow donor ... explaining, "[She] is a perfect match and she’s been spending a lot of time with me. She’s been taking shots to help her prepare."

Roberts says the procedure is scheduled for Tuesday ... and says she plans to return to work following her recovery.

"I know I’m going to have a job when I come back."

"Good Morning America" won't be left high and dry when Robin Roberts goes on medical leave in a couple months -- TMZ has learned, producers are arranging a star-studded list of substitutes to sit in for her.

As we reported, Roberts was diagnosed in April with myelodysplastic syndrome -- a serious blood and bone marrow disease -- and has already begun chemotherapy treatment ... before her big bone marrow transplant in a few months.

As for who made the temp list -- we're told producers will approach Diane Sawyer, Charlie Gibson, Barbara Walters, Chris Cuomo, Connie Chung, Joan Lunden and others. We're told each substitute will sit in Robin's chair for a full week, and each Friday the next star sub will be announced.

Given the nature of the operation, it could take Roberts 4 months to recover -- so the list will be long.

"Good Morning America" anchor Robin Roberts has announced she was just diagnosed with a serious blood and bone marrow disease ... but says she's determined to beat it.

51-year-old Roberts just released a statement saying, "Today, I want to let you know that I’ve been diagnosed with MDS or myelodysplastic syndrome. It's a disease of the blood and bone marrow and was once known as preleukemia."

She explains, "As many of you know, 5 years ago I beat breast cancer. I’ve always been a fighter, and with all of your prayers and support, a winner. Sometimes the treatment for cancer can cause other serious medical problems."

"My doctors tell me I'm going to beat this -- and I know it's true."

Roberts says she will begin pre-treatment starting today -- chemotherapy in advance of a bone marrow transplant later this year.

For the first time in 16 years, ABC's "Good Morning America" edged out NBC's "Today" in the morning show ratings last week -- and this morning, ABC News rubbed it in NBC's face ... throwing a champagne-popping victory party.

All the big swinging chicks at ABC were present ... including Robin Roberts, Diane Sawyer, and Lara Spencer -- in addition to ABC News President Ben Sherwood, Senior EP Tom Cibrowski, former "GMA" host Charlie Gibson, George Stephanopoulos, Sam Champion ... pretty much the whole crew.

We're told Robin Roberts toasted the entire "GMA" team, saying, "We're the face of it, but it's all you. Everyone in this building is a team."

Katie Couric's debut as a fill-in host this week on "Good Morning America" has pissed off some of the GMA staff, who feel it's a slap in the face to vacationing co-host Robin Roberts.

GMA is breathing down the neck of "Today" and could overtake it in the ratings this week, breaking years of NBC morning show dominance. Katie's week-long stint -- along with the fact that millions of people have their TV sets tuned to ABC because of "Dancing with the Stars" -- could put it over the top.

Our GMA sources tell us it's disgusting that honchos chose the week that Robin was on vacation to put Katie on the show. They note Robin has been co-hosting GMA since 2005 and is a big reason the show is doing so well.

As one insider put it, "They should have put Katie on when George was on vacation."

And the contingent of GMA staffers who are pissed off is large -- because Robin is well-liked. And, sources tells us, although Robin is unhappy with the Katie move, she has not badmouthed anyone.

"Good Morning America" weatherman Sam Champion got REAL excited for the forecast today -- accidentally drawing a full-blown penis on live television this morning ... and it's hilarious.

Kris Humphries is telling people he felt ambushed by "Good Morning America" this morning -- claiming he was put under the impression the interview was NOT going to focus on his split from Kim Kardashian ... but "GMA" is calling BS.

Sources close to Kris tell TMZ ... the NBA player claims he knew he would be asked about the divorce during the sit-down ... but he didn't expect to be grilled like a cheeseburger.

During the interview, Kris appears VERY uncomfortable as he's hit with question after question about Kim ... and things got downright awkward when interviewer Josh Elliot asked Kris' mother about the relationship.

We're told Kris is saying ... he only agreed to do the interview to promote his charity work and to support his mother's cooking segment on the show ... and he's livid about the way it turned out.

George Stephanopoulos could lose his "Good Morning America" anchor chair within a year to the news reader who towers over him ... this according to network sources.

The buzz at ABC is that Josh Elliott -- a former ESPN sports anchor who has been the GMA news reader since March -- is on the fast track for the anchor seat. Josh filled in on "World News Tonight" last week and network suits are in love with him.

The network will deny it's contemplating a change, but that's not what we're hearing.

The ratings at GMA have actually gone up a bit with George, so why would the network mess with the show? Our sources say the suits think Josh and Robin Roberts have better chemistry and look better together.

Our sources say the buzz is that George could go back to his old job, anchoring "This Week," especially because execs privately now admit Christiane Amanpour is a disaster as an anchor.

Not that there's anything wrong with it.

7:55 AM: An ABC News spokeswoman tells TMZ, "This is Total Nonsense."

The Parents Television Council is blasting "Good Morning America" for airing Nicki Minaj's nip slip on live TV this morning ... saying the whole thing COULD have been prevented with a 5-second delay.

TMZ spoke with Tim Winter, president of the PTC, who tells us, "For the umpteenth time in recent memory a morning news show has included inappropriate content for children and families."

He adds, "Instead of asking for forgiveness, they need to stop apologizing and implement the five second delay that so many Americans have been calling for.”
