Peaches Geldof and musician fiancé Thomas Cohen have welcomed their first baby boy, Astala, to the world.
Announcing the happy news on Twitter, Peaches, 23, daughter of Sir Bob Geldof and the late Paula Yates, tweeted: 'Yes, its true – I’M A MUMMY!!!!'
The socialite then added: 'My little boy is the most beautiful thing in this world. When he holds @tomfromscum's finger with his hand it's the sweetest thing ever.'
Peaches was due to give birth on April 24, the same day as her late mother’s birthday. Earlier this year she told Hello! Magazine she felt her mother, who died of a drugs overdose in 2000, was watching over her and she was delighted her baby was due on Paula Yates' birthday.
Peaches - whose full title is Peaches Honeyblossom Michelle Charlotte Angel Vanessa Geldof – has stuck to the Geldof family tradition of unusual names by calling her little lad Astala Dylan Willow Cohen-Geldof.
The new celebrity parents have been together since December 2010 and announced their engagement last December. Lead singer of band S.C.U.M, Thomas, 20, also posted 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.'
