Kelly Osbourne has landed the lead role in a new cartoon series.

The "Fashion Police" host has begun working on the animated programme, but refused to give details on what the "cool" show is about.

She tweeted: "Voiced the first 2 episodes of a new cartoon I play a lead roll in! I wish i could tell you what it is because its so cool #AmazingDay (sic)."

While Kelly wouldn't disclose the role, it is possible it could be part of a previously-announced venture with her parents Ozzy and Sharon and brother Jack Osbourne.

The family will be turned into animated characters in upcoming series "The F'n Osbournes."

Created by Canadian animation house Cuppa Coffee Studios, the 20-episode series will be executive produced by Sharon and Jack Osbourne, as well as Adam Shaheen of Cuppa Coffee.

Sharon said in a statement at the time: "Teaming up with Cuppa Coffee has spawned a great opportunity to produce a unique animated primetime show."
