Kelly Osbourne

Kelly Osbourne is desperate to become a mother after meeting her brother's little one.

The 'Fashion Police' host has got "baby fever" after meeting Jack Osbourne and Lisa Stelly's two-week-old daughter Pearl - who was born last month weighing in at 8lbs 6oz - and the 27-year-old star insists her niece is "perfect".

She said: "I have to tell you, I never believed in love at first sight. And then when I saw how perfect and beautiful this baby was, I lost it."

Kelly - the daughter of Black Sabbath frontman Ozzy Osbourne and 'The Talk' host Sharon Osbourne - believes she would be the "best mom ever" because she has learnt from the best teacher, her own mother.

She explained: "I'd be the best mom ever. I would. I've got great training from my mom."

Despite being warned by Jack not to spoil her niece, Kelly is already preparing to ignore him to make sure Pearl refers to her as a "cool aunt".

Speaking to Anderson Cooper on chat show 'Anderson', she added: "I want to be [the cool aunt], but I'm under strict instruction not to spoil her. But I don't think that's going to stick."
