British socialite Peaches Geldof, the daughter of Live Aid founder Bob Geldof and the late Paula Yates, gave birth to a son Astala.
"Yes, it's true - I'M A MUMMY!!!!" the 23-year-old model wrote on Twitter Saturday. The baby, with fiance Thomas Cohen, lead singer of the band S.C.U.M, is her first.
Cohen, 20, also shared the news on Twitter: "I'm a dad he is the most perfect thing ever so proud of his beautiful mum @peaches_g and overcome with joy x."
Geldof, who's full name is Peaches Honeyblossom Michelle Charlotte Angel Vanessa Geldof, revealed her son's a similarly long moniker (Astala Dylan Willow Cohen-Geldof) to Hello magazine a few weeks ago.
