What happened to Kanye West's priorities? The rapper did not make an appearance at the Louis Vuitton runway show in Paris today, and this is his favorite label. After showing up at almost twenty runway shows this season for "fashion research" and recently designing a pair of red sneakers with Marc Jacobs for Louis Vuitton menswear, why the sudden no-show? We're thinking it has something to do with his live performance on American Idol last night. With Paris nine hours ahead of Hollywood time, there is absolutely no way he could have made the 2:30 p.m. show (it would've been 5:30 a.m. in Cali). But, really, American Idol over Louis Vuitton? Not only did he share the stage with thirteen karaoke hopefuls, he shared the spotlight with Kelly Clarkson. Contractual obligations ... they can be so heartless.
