Celebutante Paris Hilton may have failed as a reality star and singer, but that doesn't mean she's ready to call it quits just yet. After months of anticipation, the bubble-headed blonde finally debuted her new song with boyfriend AfroJack. The 31-year-old made a memorable showing at the Sao Paulo Pop Music Festival. Prior to her appearance, she Tweeted, "Busy day preparing for my show tonight. I'm so nervous and excited. I can't wait to get up there and see #SaoPaulo dance!" Before playing her new song, she tried to butter up the thousands of concert goers in the crowd, telling them, "I've partied all around the world ... the best parties ... but I've never seen anyone party like you guys do in Brazil." Unfortunately, all the butt-kissing in the world couldn't save Hilton from herself. She was booed as she took the stage to perform. And it wasn't just the audience heckling Hilton. World-famous DJ Deadmau5 Tweeted, "It's over. To be fair... the mayans saw this sh*t coming."
