Kelly Osbourne has admitted that she could be ready to have a baby.

The 'Fashion Star' host claimed she was feeling broody two weeks after her niece was born.

The 27-year-old E! star's brother Jack witnessed his first child with Lisa Stelly being born in April, and his sister has now revealed that she wants a child of her own.

She told Anderson Cooper on his TV show Anderson: ''I've got baby fever after I saw [her]. I'd be the best mum ever. I would. I've got great training from my mum.''

The outspoken star even admitted that the latest edition to the Osbourne family, Pearl Clementine, has opened up her mind to new beliefs.

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 and is, I lost it. I cried more than anyone else.''

As a first-time auntie, Kelly also said that she has been warned not to surround the young child with treats, however she is unsure whether she'll be able to resist.

She added: ''I'm under strict Instruction not to spoil her but I don't think that's going to stick.''
