Former Radio 1 DJ Fearne Cotton has given birth to a baby girl.
The 33-year-old announced on Twitter: "Jesse and I are over the moon and buzzing with love, as our baby daughter Honey Krissy Wood came into the world this morning."
The name Krissy is likely to be a tribute to husband Jesse Wood's mother, Krissy Findlay, who die in June 2005.
Friends including Holly Willoughby, Rochelle Humes and Sophie Ellis-Bextor have tweeted their congratulations.

TV presenter Willoughby wrote: "Congratulations beautiful lady @Fearnecotton so so excited for you all. Can't wait to meet little honey... Love you."
Cotton and her husband, who married in July last year, are already parents to two-year-old son Rex.
The couple announced their second pregnancy on Twitter in February and Cotton recently took to the social media site to reveal that Rex had requested an unusual name for his new sibling.
"Me -'What do you want to call the baby when it's born, Rex?' Rex -'Bob the builder baby'," she tweeted last month.
