Who's That Chick ? (feat. Rihanna)

This high-energy David Guetta-produced number sees Rihanna returning to the world of dance music after the darker tracks she recorded for Rated R. The song leaked online on September 17, 2010. Guetta said to MTV News regarding helping Rihanna return to dance music: "Well, you know, I'm a DJ, so I make beats that make you wanna dance. And I think she was one of the first to do that in that urban world, so you know, I think it would be good for her to do it again."

Guetta originally previewed the heavily Auto-Tuned track earlier in 2010 on French radio.

The colorful Japanese-pop inspired video was directed by Jonas Akerlund (Lady Gaga's "Paparazzi" and "Telephone") and was filmed for an online commercial for Doritos. It shows a fun-loving Rihanna making her way through a rainbow fantasy world clad in a multicolored ensemble.
