Kanye WestHere we go again. According to Page Six, Kanye West -- no stranger to throwing an imposing adult temper tantrum -- flipped out at Los Angeles' LAX airport when he and his assistant were placed in business class instead of first. A witness told Page Six that West, who was on his way back to New York after recording the 'We Are the World' remake, "wanted to be bumped up" and eventually got his way. Makes sense.

Prior to his alleged airport conniption (not to be confused with 2008's altercation with a paparazzi), West joined more than eighty of today's biggest stars at the Jim Henson Studio and Soundstage in Hollywood, the site of the 1985 'We Are the World' recording. Penned and produced by Michael Jackson and Lionel Richie, the original 'We Are the World' featured Stevie Wonder, Diana Ross, Paul Simon, Bruce Springsteen, Bob Dylan and Ray Charles. The remake boasts a contemporary cast of characters with Snoop Dogg, LL Cool J, Lil Wayne, T-Pain, Drake, Swizz Beatz, Kid Cudi and more.

'We Are the World - 25 for Haiti' will premier during the 2010 Vancouver Winter Olympics Opening Ceremonies on Feb. 12, with all proceeds going towards Haitian earthquake relief efforts.
