MARIAH CAREY'S CLEAVAGE STEALS THE SHOW: Oh. Mah. Gawd. You have to figure some basic laws of physics had to have been broken to keep MARIAH CAREY from popping out of her dress this weekend. Saturday night’s BET Honors was meant to be a celebration of the outstanding careers of the legendary Queen of Soul ARETHA FRANKLIN, Motown founder BERRY GORDY and rapper ICE CUBE, but it was Mariah's eye-popping dress that stole the show.

More specifically, Carey’s cleavage! (PHOTO) (PHOTO) (PHOTO) Am I the only one who thinks Mariah was channeling Jessica Rabbit?

SHIA LABEOUF WALKS OUT OF PRESS CONFERENCE, WEARS PAPER BAG ON HIS HEAD: SHIA LABEOUF displayed some bizarre behavior over the weekend. Shia – who recently declared he was retiring from public life – was at a press conference in Berlin, Germany, to promote his latest movie but his appearance was short lived.   .

After a reporter asked him about all the sex scenes in the movie, LaBeouf replied, “When the seagulls follow the trawler, it is because they think sardines will be thrown into the sea.” He then left without an explanation. The quote, by the way was not an original. It was first uttered by a French soccer star back in 1995. Best guess; he was inferring the media are the seagulls, and they gather around him because they think he'll give them something juicy. Which he actually did.

Shia's crazy antics continued later that night at the red carpet premiere, where he showed up with a paper bag over his head that read, "I am not famous anymore." Note to Shia: Retiring from public life means that you stay away from press conferences and red carpet affairs. (PHOTO)

TODAY IN JUSTIN BIEBER NEWS: Another day, another problem for JUSTIN BIEBER. The Federal Aviation Administration has announced plans to investigate the claims that passengers aboard the private jet Bieber took from Ontario to New Jersey last week interfered with the flight crew en route to the Super Bowl. The crew alleged that Bieber and his entourage, which included the singer's dad, Jeremy, smoked so much pot during the flight that the pilots felt it necessary to don their oxygen masks.

 Under FAA regulations ... “No person may assault, threaten, intimidate, or interfere with a crew member in the performance of the crew member's duties aboard an aircraft.” Under a civil statute, violators face penalties of $11,000 to $27,500. Under a criminal statute, violators face a maximum of 20 years in prison and fines up to $250k. So far, the FAA has declined to say whether they were alerted by complaints from the pilots, by media reports, or the investigating officers.

Meanwhile ... video of Bieber being searched after he was arrested in Miami last month hit the web over the weekend. And Justin's lawyers don't want any more of it released. They told a judge, "While in custody at the Miami Beach police station the defendant was captured on videotape in various states of undress which show intimate personal parts of the defendant's body."
