Watch: Jimmy Fallon and will.i.am Made an ‘Ew!’ Music Video

Ew! with TSwift
Taylor Swift and Jimmy Fallon are little girls for Ew! on 'The Tonight Show.'
You know how Jimmy Fallon likes to dress up like a tween and have his guests do the same for his “Ew!” sketch?

Well now there’s a music video starring Sara (that’s Fallon’s alter ego) and her BFF mr.i.am, played by none other than will.i.am.

In the Tonight Show video, the pair rap about things like Sally being mad at Iggy because of Iggy’s booty, duck lips, FaceTime, roly poly caterpillars and moldy windows, among other things that fit under the Ew! category.

Recent Ew! guests have included Taylor Swift, Seth Rogen, Zac Efron and First Lady Michelle Obama.
