Celebrity News:

TMZ has learned that Amy Winehouse is set to headline the mtvU Woodie Awards in New York City next month ... unless, of course, she doesn't.

The "Rehab" singer, who recently canceled her North American tour, is up for Woodie of the Year (whatever that is), and sources close to MTV tell us that she'll perform at the November 8 awards at the Roseland Ballroom.

Assuming Amy shows up -- and there's no guarantee -- the show airs November 15 on mtvU and mtvU.com
