Peaches Geldof has confirmed that her son with fiance Thomas Cohen is due on April 24, the same date as her mother's birthday.
Her mother, TV presenter Paula Yates, died of a heroin overdose in 2000 aged 41.
The 22-year-old last month announced that she was engaged to S.C.U.M frontman Thomas Cohen.
''I feel like it's a little wink from my mum — her way of sending a message to let me know she's watching over me and my baby.''
"It was amazing for me when they told me that, very emotional and touching and just really beautiful. I was so happy."
She told Hello! magazine: "Oh my God, he was so happy, especially as I'm having a boy. The poor man's been surrounded by women up till now.
"I didn't realise how over the moon he would be. He's always been very supportive of me but he was really overwhelmed and emotional."
Geldof was divorced at the age of 19 after marrying musician Max Drummey back in 2008.
The pair eloped in Las Vegas in August 2008 but announced their split in February 2009.
