London, Jan 24 (Agencies): Reality star Kelly Osbourne is set to replace 'Gossip Girl' actress Taylor Momsen as the new face of pop diva Madonna's clothing range.

The pop superstar recently launched an online search for the next poster girl for her 'Material Girl' line, encouraging fans to vote for their favourite through the brand's website.

The 26-year-old daughter of rocker Ozzy Osbourne is said to be taking the lead to front the brand for teens, reported Mirror online.

Kelly, who recently slimmed down to a size eight, is an inspiration to the queen of pop's 14-year-old daughter Lourdes who has an active contribution in the designer range.   

"A lot of my inspiration comes from her," Lourdes said.

And Kelly returned the compliment, saying, "To be thought of as an inspiration in that way is brilliant. I hope little girls look up to Lourdes because she doesn't dress too grown up and she always looks so stylish."

"Kelly's always been a massive fan of Madonna and recently heard Lourdes idolised her, which she was very flattered by. It's a huge coup," said a friend of Kelly.
