Congratulations to James Corden and his wife Julia Carey who have welcomed their third baby!
In the early hours of the morning, James' wife Julia gave birth to their third child, a baby girl.
But James, who is already dad to Max, six, and three-year-old Carey with Julia, was caught off guard, and had to find a last-minute replacement for his evening TV show, The Late Late Show With James Corden.
Luckily, pop star Harry Styles was on hand to take over!
Taking to Twitter, James wrote: "Today we welcomed a beautiful baby daughter into the world. Both she and her mother are doing great. We can’t stop smiling."
He also thanked Harry for stepping in at the last minute to host his show, as he was given just two and a half hours notice.
Harry also revealed the news to the audience, saying: "Just half an hour ago, James and his wife Jules had a beautiful baby girl. Congratulations!
"In fact, I was just at the hospital before I came to fill in and she looks a lot like James. Mainly because James looks like a giant baby!"
Back in September James Corden revealed the gender of their baby, saying: "She’ll be arriving Christmas - we're very excited."
He added: "It will be great, lovely. We're having a little girl, it’s going to be terrific."
Congratulations to the family!
