The news was broken last night by HELLO magazine's editor Rosie Nixon on her Twitter page, where she wrote: "Big congrats @MrJackO & @lisamarstelly who today welcomed baby Pearl into the world."

Last November, Jack, 26, revealed on that he was "excited" about becoming a dad for the first time, and said it was a "very good thing" that his aspiring model and actress girlfriend Lisa, also 26, was expecting.

"It wasn't planned," he said, before adding: "It's going to be a new chapter in my life!"

Like you wouldn't believe, Jack. Like you would NOT believe!

Congratulations and best wishes to the three of them.
