The TV presenter and model delivered son Phaedra on Wednesday by elective Caesarean section - the date her mum Paula Yates would have turned 54.
The Sun reports that proud dad Tom was with Peaches when Phaedra was born, and her sisters Fifi, 30, Pixie, 22, and half-sister Tiger Lily, 16, were all at the hospital to support her.
Peaches had wanted her first little boy, Astala, delivered on the 24th last year, but he couldn't wait, arriving on the 21st.
A source close to Peaches and Tom told the Sun last night: "They are absolutely over the moon about their new arrival. It all went smoothly and Peaches will be in hospital for a while to recuperate. Bob is absolutely over the moon - the whole family are."
The mole added that the couple were 'particularly pleased about the significance of the date as it makes Peaches feel she is keeping her mum's memory alive'.
Prolific tweeter Peaches has yet to upload any pics or comment on her new little boy, but given her love of sharing photos of Astala and adorable dog Parpy, we bet it won't be too long!
Congratulations to Peaches and Tom!
