Wee're sure plenty of people saw Selena Gomez co-hosting the 2011 MuchMusic Video Awards this past Sunday, June 19. However, some of her fans might have missed her on another program that night, Disney's original sitcom 'So Random.'

Selena Gomez and her backing band the Scene made a guest appearance on the show, which is a spin-off of Demi Lovato's old show 'Sonny With a Chance.' The show is about a teens that are members of a sketch comedy show a la 'Saturday Night Live,' and the wild antics they get into on and off the set.

Gomez and the Scene performed the hit song 'Who Says,' featured on their upcoming album 'When the Sun Goes Down.' On the show, Gomez wore a flowy, white top, which is a staple in her wardrobe, skin-tight jeans, hoop earrings and a dog-tag necklace as she sang into her bedazzled microphone. Even though we expected this since it is a taped show, Gomez is obviously lip syncing the lyrics to 'Who Says,' which is a bit disappointing.

Check out Selena Gomez and the Scene performing on 'So Random' below, and if you are trying to catch Selena Gomez on her summer tour, you can check out a full list of dates here. Gomez will drop 'When the Sun Goes Down' this upcoming Tuesday, June 28.
