Peaches, 23, and her husband Thomas Cohen, 21, are already proud mummy and daddy to six-month-old Astala - and the young mum admits that finding out she was pregnant again so soon was a 'quite a shock'!
Speaking to Hello! magazine, Peaches says she is three and a half months along with her second son - who she and Tom have already named Phaedra.
"I 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?" she said, but added that her devoted husband soon made her cast any doubts aside.
"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. There are massive benefits to having two children so close together," she said.
Peaches' lovely news comes just a few days after she told Elle magazine that she once feared she would never have children after being diagnosed with Polycystic Ovary Syndrome after suffering an ectopic pregnancy three years ago.
Aw, such wonderful news - and double the amount of Twitter pics to look forward to!
