Michael Sheen's new daughter was born just a week ago. Him and his partner Anna Lundberg have decided to name their firstborn 'Lyra'.
At 50, the Welsh actor is already the father of 20-year-old Lily from his previous partner Kate Beckinsale.
The Good Omens star shared a picture of Lyra in her tot being carried out the hospital.
He tweeted: "Happy to say that at 8:41 am on Monday September 23rd our beautiful daughter Lyra was born. Thank you so much to Louise & all the brilliant midwives at both the Singleton and NeathPortTalbot hospitals.(sic)"
Michael also thanked his fans for their "wonderful" messages in the wake of his happy news, and admitted that adjusting to having a newborn in the house has involved not much sleep and an "extraordinary" amount of nappy changes.
He wrote: "On behalf of Anna and myself thanks to everyone for your lovely messages of congratulations. It's been a wonderful, bleary-eyed week full of love and kindness and extraordinary poo. #NotReferringToMyself (sic)"
The Welsh star's father, Meyrick, confirmed the baby had been born a few days ago.
He added: "We are thrilled to bits, over the moon."
The 'Passengers' star and Anna only shared their pregnancy news in July.
Michael wrote on Twitter at the time: "Very happy to let everyone know that my partner Anna and I are expecting a little angel of our own. (Just to be clear - we're having a baby!) #nottheantichrist (sic)
"The 'Midnight in Paris' star recently admitted he isn't looking forward to the "sleepless nights" that are upon him.
He admitted: "There are too many good things to name about becoming a dad at 50. The sleepless nights ain't one of them."
