Srsly? The host and the Black Eyed Peas frontman donned dresses, wigs, polish and — in’s case — some throwback orthodontia on The Tonight Show Starring Jimmy Fallon this evening. Watch as they rap about butts, implants, duck lips and things that make you go “ew.” And more. So much more. Haters gon’ hate, but Sara and tots don’t care. LOL!
