Speaking of unwelcome guests... Nobody was more unwelcome than Kanye West at the 2009 VMAs. In accepting her award for Best Female Video, Taylor Swift was overwhelmed with joy, almost speechless for one of her first mainstream accolades, until The Louis Vuitton Don had something on his mind that could not wait. Though it's a smart bet that Beyoncé and Taylor felt it could.
West was already on shaky ground with MTV for making a stink numerous times with the VMAs. First with not winning, classic Kanye, then he had a problem with letting an unready Britney Spears open the show over him in 2008. This was supposed to be the straw that broke the camel's back as he was rumored to be banned from the VMAs. Until the next year, where he premiered his first single from his best-reviewed album to date, My Beautiful Dark Twisted Fantasy.
After a whirlwind apology tour and throngs of hate-filled mobs directed Kanye's way, all three artists involved would be successful post-stage-crash and can look back at this moment with a shrug, but there probably isn't a collaboration coming anytime soon.
