Peaches Geldof is pregnant with her second child just six months after the birth of her son Astala, she has announced.
The former wildchild said she and her musician husband, Thomas Cohen, have already decided to name the boy Phaedra.
Peaches, 23, admitted that she had a feeling of "momentary panic" when she discovered she was pregnant again.
She told Hello! magazine: "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.
"Finding out I was pregnant again so soon was quite a shock."
She said: "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?'
"But Tom was so supportive and relaxed, it banished my doubts and I started imagining the two boys growing up together as the best of friends. It will be great for Astala to have Phaedra to play with."
The daughter of musician Bob Geldof told the magazine that she only took a pregnancy test after getting a "tummy".
"When the test came up positive, Tom remembered that I'd been craving these particular sour sweets, which I've only ever eaten when I've been pregnant. He said 'How could we not have guessed?'."
