Selena Gomez and the Scene Perform ‘Who Says’ During 2011 MuchMusic Video Awards

Selena Gomez played double duty Sunday night, June 19, during the 2011 MuchMusic Video Awards, as she served as the co-host and performed her latest single, 'Who Says.'

Perched on a red plush velvet couch wearing a sexy, slinky black and red number, the singer gave her fans a taste of what's to come from her forthcoming album, 'When the Sun Goes Down,' slated to hit stores on June 28.

As she exited the "bedroom" portion of her set and entered onto a "rooftop" scene, the barefooted singer twirled around the stage performing the tune, as the stars on the backdrop twinkled and lighting strikes flashed about.

As the crowd sang along, Gomez worked the stage front, touching as many hands as she could reach while the fans quickly snapped photos of their favorite star on the rise.

Earlier in the evening, Gomez helped present the MuchMusic Video Award show's first trophy for International Video of the Year by a Canadian, which was a tie between Drake (‘Find Your Love’) and Gomez's boyfriend, Justin Bieber (‘Somebody to Love Remix’).
