Kelly Osbourne Says It's 'Fun' Being the New Material Girl

Reality TV star Kelly Osbourne has become the new face of Madonna and Lourdes Leon's fashion line, Material Girl -- and Osbourne tells "Extra" she's loving it!

"It was so much fun to get to work with Madonna, but especially Lourdes. I think she's a fantastic girl," gushed Osbourne. "Lourdes picked out all the outfits, and Madonna oversaw everything and made sure the looks were going in the right direction. But really it isn't just a publicity ploy. Lourdes does most of the work."

Osbourne, who shed 60 pounds when she competed on "Dancing with the Stars," replaces "Gossip Girl's" Taylor Momsen, who helped launch the new line last fall.
