Fearne Cotton has become a mum - the Radio 1 DJ has announced - to a boy called Rex.
The TV presenter and her partner Jesse Wood announced the news of the baby's arrival on Twitter.
"Jesse and I are over the moon to announce the arrival of Rex Rayne Wood born on the 21.2.13," she said.
The star, who has been on maternity leave from her Radio 1 show since just before Christmas, added two heart symbols and wrote "beyond in love".
Fearne, 31, has been dating Jesse, the son of Rolling Stones star Ronnie Wood, since 2011.
Model and musician Jesse has two children, Arthur and Lola, from his marriage to Tilly Wood.
