Peaches has become a mum for the first time, after giving birth to a baby son, named Astala, this April.

She and Thomas announced their happy news through Twitter, with 23-year-old Peaches writing:

"Yes, it’s true – I’M A MUMMY!

"My little boy is the most beautiful thing in this world. When he holds @tomfromscumÂ’s finger with his hand its the sweetest thing ever."

Geldof and Thomas got engaged in 2011 and announced they were expecting their first child together weeks later.
