will.i.am and Jimmy Fallon Play Teenage Girls in 'Ew!' Music Video

OMG! Jimmy Fallon and will.i.am transform into their teenage-girl alter-egos, Sara and mir.i.am, in the music video for “Ew!” which premiered on “The Tonight Show.” The BFFs hit their high school dance and rap about things they find “Ew!” like silicon butts, ratchet outfits, and most of all, Sara’s stepdad Gary.

“I am not hating, I am merely conversating with my BFF Sara,” raps mir.i.am, who sports headgear and a pink backpack.

“Ew!” is available for download on iTunes with the proceeds going to the SeriousFun Children’s Network and i.am.angel Foundation.
