Kelly Osbourne is the New Face of Madonna's Material Girl Fashion Line

Kelly Osbourne's has been named the new face of Madonna's Material Girl fashion line.

Osbourne, who once called herself an "ugly duckling," replaces 'Gossip Girl' star Taylor Momsen, according to a tweet from the company.

Material Girl is a year-old juniors design collaboration between the iconic music superstar and 14-year-old daughter Lourdes. It's sold exclusively at Macy's.

"Material Girl is thrilled to confirm that Kelly Osbourne is the new face for 2011. We will be sharing all the details on this exciting new campaign in the coming weeks," her rep confirmed in a statement.

Material Girl launched in 2010 with rebellious Momsen as its face. Late last year though, Lourdes blogged that the label was "desperately seeking" a new face.

Osbourne, who slimmed down considerably after an image-altering turn on ABC's "Dancing With the Stars," has updated her look from goth to glam.

"I've spent the last few years trying to figure out who Kelly Osbourne is, from addiction to awards and fashion faux pas," she writes on her official blog.

Things seem to be looking up for Osbourne, who earlier this month was seen with British musician Rob Damiani, after a long funk from breaking up with Luke Worrall last summer.

Taylor Momsen May Be a Material Girl No More

Despite landing campaigns for Madonna's juniors line Material Girl and John Galliano's most recent fragrance, Parlez-Moi d'Amour, Taylor Momsen is currently without a modeling agency, having been dropped by IMG.

Now it appears that Momsen is no longer affiliated with Material Girl—or won't be for long, anyway. According to Material World, the Material Girl fashion blog, the search is on for the next spokesmodel.

Fans of the Macy's line are invited to suggest the next Material Girl by write-in vote on the brand's website. Who do you think should be brand ambassador? Our money's on Madonna's daughter Lola...she's already writing the best Material World blog posts, anyway.

Madonna Happy to Let Daughter Lourdes Take the Lead in Material Girl Line

It was a night of lace tights, skirts, and mother-daughter bonding for Madonna and daughter Lourdes Leon, 13, as they celebrated the launch of their Material Girl clothing line Wednesday night at Macy’s Herald Square in New York City.

Despite being a fashion icon, Madonna was content to take a backseat when it came to choosing the items for the Material Girl girl.

“Lola did most of the work. I just kind of hung out in the background and went, ‘That’s nice,’ but she pretty much did all of the work. I was just overseeing it,” she said.

But when your mom is Madonna and you’re creating a fashion line for teenage girls, it isn’t always that simple. “There are some definite pieces [inspired by my mom]. The tulle skirt because that’s like her thing—she made that. The necklaces, the gloves, the lace tights, the combat boots…that tough girly thing,” Lourdes told People Magazine.

As for the items in Mom’s closet that she covets most? “All of her shoes are ridiculous! I love to try on her [Christian] Louboutins,” she said.

Also on hand for the celebration was Material Girl face Taylor Momsen. “It was such an honor to be chosen by Madonna and Lola. They’re such talented people and I’m just ecstatic,” gushed the Gossip Girl star.

The night concluded with the three ladies gathering on the fourth floor of Macy’s, as dancers performed and a DJ spun many of Madonna’s songs.

“Lola has been so inspiring and it’s been so great to watch her focus, her determination.” Madonna said. “I’ve achieved many things in my life, but I have to say watching my daughter make her dreams come true and achieve her goals is more exciting than anything I’ve ever done
