Peaches Geldof wants to have a baby by the age of 25.

The 22-year-old socialite - the daughter of musician and Live Aid founder Bob Geldof - is keen to start a family and ideally she'd like to become a mother in the next three years.

Peaches - who is currently dating 19-year-old S.C.U.M musician Thomas Cohen - said: "I would like to be a mother soon. I'd like to be a young mum, so it's not something I'd want to wait too long for. I don't know, quite soon, hopefully around 25. I'd love to have a baby."

The TV star - whose mother is the late Paula Yates, who died from a heroin overdose in September 2000 - believes she will be a laidback parent but with some definite rules for her Offspring.

Speaking at the Carphone Warehouse Appy Awards in London, she added: "I think I'd be a very liberal mum but with a strict set of rules. I don't want a wayward junior Geldof.

Peaches - who has three sisters, Pixie, Fifi Trixibelle and Tiger Lily - is rumoured to have experimented with heroin and has previously confessed to trying drugs when she was younger.

She has said in the past: "I have had bad experiences with drugs. The experiences aren't ones I want to repeat but I was growing up. I wasn't hugely into drugs, I'm not Amy Winehouse and I never have been."
