If you wanted to see Jimmy Fallon and will.i.am in drag, tonight's your lucky night. The two debuted the hilarious song and video "Ew!" on The Tonight Show. In it the two play a couple of teenage girls getting grossed out by everything and anyone at a high school dance. 

Fittingly, will.i.am goes even crazier than Fallon with headgear, green and flowery glasses, pink headband and backpack, and adorable pigtails. 

Meanwhile Fallon shows off his broad shoulders in a purple dress and also rocks a blonde wig, braces, and pink tights. 

Ew indeed. 

You can already snag the single on iTunes.
