The daughter of Bob Geldof has revealed she pregnant with her first child. The news comes just a month after she and Cohen announced they were engaged.

"Peaches Geldof and her fiancé Thomas Cohen are delighted to announce that Peaches is pregnant with their first child," her spokesperson confirmed.

"Peaches is utterly thrilled and they have the full support of both of their families who are equally excited for the baby's arrival."

The socialite and Cohen met four years ago but only recently began a relationship. Speaking of her engagement, Peaches said: "We first met four years ago and we bumped into each other last Christmas (2009) on Portobello Road in Notting Hill, London, and started dating again - and that's also where he asked me. It was romantic. I'm really happy. But we don't want to get married for a couple of years yet."

Peaches was previously married to Max Drummey who wed in a Las Vegas ceremony after a whirlwind 10-day romance. Their marriage ended after just six months.
