The Tonight Show premiered its first music video Monday! Jimmy Fallon and will.i.am performed as their teenage-girl alter-egos (Sara and mir.i.am) while rapping about things they think are just “Ew!” Wearing wigs, braces and dresses, the BFFs weighed in on the topics that matter most to young girls, including bread bowls, duck lips, FaceTime and “impleggies” (butt implants.) Fallon is clearly very excited by his latest musical endeavor, tweeting, “#ohmygross,” “Get Ew! on the radio!!” and “#Ew! Please request this to your local DJ?” For $1.29, Fallon and will.i.am’s “Ew!” is available for download on iTunes. Proceeds from the sale of the song will benefit the SeriousFun Children’s Network and i.am.angel Foundation.
