Bad Boy artist Janelle Monae performed at the 2010 ESPY Awards in Los Angeles last night to a packed crowd that included many of the sports and entertainment world's biggest stars. The audience was in for a surprise however, when the Grammy-nominated singer reappeared in a comedy sketch with funnyman Will Ferrell, who was performing as a character named Jeff Vuvuzela, inventor of the ubiquitous mouth horn that plagued accompanied this year's World Cup.

"Kids used to make fun of my voice growing up, but who's laughing now? For the last month, an entire country was blowing Vuvuzela," Ferrell quipped.

"I'm the most popular sound in the world!" Ferrell continued. "My real passion is music. I just recorded an album with the amazing Janelle Monae. Janelle, lets do track 40. Gotta give the people what they want!"

Monae then dueted with Ferrell on a "Jeff Vuvuzela remix" of Roberta Flack's 'Tonight I Celebrate My Love,' before kissing and taking a bow.
