Kelly Osbourne is a material girl.

The E! Fashion Police co-host, 26, will take over the spokesperson role previously held by Gossip Girl star Taylor Momsen.

"Material Girl is thrilled to confirm that [Kelly Osbourne] @MissKellyO is the new face for 2011!" the fashion line Tweeted.

Material Girl, designed by Madonna and her 14-year-old daughter, Lourdes, launched last summer with Momsen, 17, as its first spokesperson. On January 11, Lourdes, who writes the fashion label's blog, announced the line was "desperately seeking" a new face.

Osbourne, it seems, was the natural choice. "Kelly's always been a massive fan of Madonna and recently heard Lourdes idolized her, which she was very flattered by. It's a huge coup," a source told Britain's Sunday Mirror.

The replacement is the latest hiccup for Momsen: In November she was reportedly suspended from Gossip Girl due to bad behavior. And in a December interview with Revolver magazine, Momsen blamed her parents for her "miserable attitude," which she later apologized for.
