Miley Cyrus helped Kelly Osbourne celebrate her 27th birthday at the Little Door nightclub in Los Angeles.

Ms. Osbourne, who held on tight to a grungy-yet-sexy new guy, was thrilled to have the Disney darling at her late-night fiesta. Kelly Tweeted:

    "Having the best birthday with @MileyCyrus I'm so happy she came!"


While the formerHannah Montana star wore a long red skirt and animal print blouse, the birthday girl opted for black pants and a drapey white shirt. Not sure the fashion police would approve of this one!
