The Oscars

11:40 AM PT -- Sources connected to the party tell TMZ ... Kwanten was invited to the party as a guest of George Clooney and his GF Stacy Keibler ... and SHOULD have been on the list.

We're told party organizers are trying to find out how Kwanten's name was left off the list ... but it's clear the actor wasn't trying to crash the party uninvited.

TV stars get no respect on Oscar night ... just ask "True Blood" star Ryan Kwanten ... who was embarrassingly REJECTED at the door of a huge Academy Awards party ... and TMZ caught the whole thing on tape.

Kwanten -- sporting a fancy bow tie -- arrived to Craig's in Hollywood with a handler last night ... when they came face-to-face with the security team guarding the front door.

Kwanten and his buddy insisted they were personally invited by Craig himself ... but the bouncer wasn't buyin' it.

Kwanten's handler even whipped out his cell phone and got someone important on the phone to vouch for him ... but when he gave the phone to the bouncer, the security guy STILL wouldn't let him in.

Eventually, Kwanten and his buddy took the note and walked away ... but not before the handler asked the bouncer which company he worked for ... insinuating that heads would ROLL over the rejection.

Don't worry Ryan ... at least you're still pretty.

It's a good bet Michelle Obama was not the first person to open the envelope for Best Picture ... and she may not have been the second, third or fourth.

It is inconceivable an envelope from the outside world could end up in the White House, in the First Lady's hands, without a thorough, inside-and-out inspection.

The upshot ... Michelle may be First Lady, but she wasn't first to know "Argo" took home the big prize.

We did some digging to find out exactly who handled the goods. The First Lady's press office said they'd call around to find out the answer and get back to us, but so far that hasn't happened.

Ben Affleck could probably use a ladder to get out of that hole he dug himself into at the Oscars last night when he called out the imperfections in his marriage to Jennifer Garner during his "Argo" victory speech.

You could hear the nervous laughter from the crowd when Affleck -- who was racing through his speech -- said, "I want to thank my wife ... for working on our marriage for 10 Christmases."

We respect his honesty ... and Garner was smiling when the camera cut to her ... but how do you think the comment went over at home, behind closed doors?

When he wasn't taking up all of Ben Affleck's victory speech time -- "Argo" producer Grant Heslov says he managed to avoid THE GREAT TOILET DISASTER at the Oscars last night using a time-tested technique ... he held it.

Heslov -- along with his wife Lisa -- took his freshly scored Best Picture statue out to party at Craig's in Hollywood last night ... when we asked about the plumbing catastrophe at the Dolby Theatre.

Heslov told us he wasn't "personally" affected ... but he's one of the lucky ones.

As we first reported, the lobby was soaked in toilet water after a water pipe burst in one of the bathrooms.

So far, officials have not revealed the person who dropped the nasty toilet-bomb that destroyed the pipes ... but our money's on Anne Hathaway.

Someone reportedly unloaded in one of the bathrooms at the Oscars and flooded the lobby ... TMZ has learned.

We're told a water pipe burst inside the Dolby Theater in Hollywood, just before the opening curtain was pulled. The custodial staff handled the situation with vacuums.

No one on stage has mentioned it ... but it's apparently quite a thing.

L.A. City Fire did not know the nature of the leak, but there is one report from someone on scene that a toilet triggered it.

Even with Justin Bieber hair, Oscar winner Charlize Theron is always stunning.

Flawless.

Kristen Stewart carefully made her way down the red carpet at the Oscars with the help of Robert Pattinson Rupert Sanders crutches.

With his gorgeous wife Jennifer Garner at his side, Ben Affleck is ready to not win the award for Best Director at the Oscars on Sunday.

Looking great is the best revenge.

Nicole Kidman made a pit stop at the La Brea Tar Pits on the way to the Oscars.

After the brief blip that was her Mrs. Roper Grammy getup, Adele went back to wearing her black dresses to the Oscars on Sunday.

The biggest star at the Oscars ... is Melissa McCarthy's hair.

Not only is Melissa a presenter tonight, but her movie "Identity Thief" is #1 at the box office for a second week.

Looking fabulous in a blue gown, Robin Roberts was all smiles as she readied to cover the Oscar red carpet on Sunday.

On Wednesday, Robin returned to "Good Morning America" after undergoing a bone marrow transplant to treat a blood disorder.

She's back and working overtime.

With the 85th Academy Awards just hours away, travel back in time and check out the best and worst looks from last year's red carpet.

Law enforcement is on extra-high alert for tonight's Oscars ... given the wave of gun violence across the country ... various law enforcement sources tell TMZ.

The LAPD's official position is that they are always vigilant at Oscar ceremonies and security is tight. But multiple law enforcement sources tell us ... there is "an extra knot" in security this year because of all the shootings that have made big news in the U.S..

One LAPD honcho tells us ... the general climate right now is intense: "When someone from the city gets fired, the city manager of the department calls because they're scared the person who was fired will go postal." The source adds, "People are going crazy with fear."

On the stalker front ... we're told the LAPD gives a private security company -- Security Industry Specialists (SIS) -- an information packet of stalkers who are harassing stars who are attending the Oscars. The packets include pictures of the stalkers, which are distributed to security in the field.
