Congratulations are in order for David Tennant and his wife Georgia, who have welcomed their fifth child together.

Georgia revealed the news with an Instagram post showing her husband carrying their newborn in a carrier, alongside a photo of his Good Omens co-star Michael Sheen, who welcomed a child of his own back in September.

“An angel, a demon and a couple of babies,” she captioned. “What could possibly go wrong?”

Plenty of fans (and fellow Doctor Who star Tracy Ann Oberman) sent their congratulations and best wishes to the couple in the comments.

David and Georgia met on the set of Doctor Who series 4 episode ‘The Doctor’s Daughter’, where Georgia (who is the daughter of former Doctor Peter Davison) played The Doctor’s genetic clone/daughter.

David is the father of four of Georgia’s children, while he adopted her older son Ty from a past relationship after they married in 2012.

Recently, the former Doctor opened up about how the fame of the show left him feeling:

“Intimidated” and “scared”. “The way you imagine it’s going to be is not the way it is at all,” David said.

“It’s much more exposing, and the imaginative leap you’ve had that it will give you status or make you invulnerable is all wrong. It makes you very vulnerable, and very raw.”

Doctor Who airs on BBC One in the UK and BBC America in the US.
