Amy Winehouse looked like an absolute monster on Leno the other night with her hair beehived into oblivion. The missing tooth only added to her trashy vamped-up persona. She seemed sort of out of it, spacing out with a completely blank stare, occasionally throwing in some doo-wop dancing, but her voice sounded unbelievably good. And the male back-up singers’ choreographed dancing was pretty incredible, too.

Winehouse, who considers herself a hip-hop artist for some reason, has teamed up with Jay-Z, who remixed her hit, “Rehab.” Winehouse told MTV News: “the Jay-Z remix is wicked. I’m flattered that he liked [the song] enough to do something with it.”
