The 23-year-old socialite - who already has seven-month-old son Astala - is expecting another baby boy with her rocker husband Tom Cohen, but admitted she is nervous about becoming a mother again so soon. Peaches - who is into her fourth month of pregnancy - told Britain's HELLO! magazine: "Finding out I was pregnant again so soon was quite a shock. Tom was so happy. He loves being a dad so much and is brilliant with Astala, who totally adores him, so he was over the moon. "I, on the other hand, did have a momentary panic and go, 'Oh my god, we're going to have a one-year-old and a one-month old! How will we cope?' " Peaches plans to name her son Phaedra, and she explained: "It's a name that comes from an ancient Greek play. But it also features in a song Tom and I both love called 'Some Velvet Morning' by Lee Hazlewood."
