Hollywood star Michael Sheen announced in a cheeky tweet this past Wednesday that he's expecting a baby with his girlfriend, Swedish actress Anna Lundberg.

Quipping the biblical themes existing in his series Good Omens, the actor wrote, "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"

The 50-years actor's, 25-years Anna Lundberg, is a Swedish actress who lives in New York. Lundberg has attended N.Y.C.’s American Academy of Dramatic Arts and has accomplished several theatre performances, including Gloria, Othello, and Spring Awakening.

While Michael is well-known for his roles in Master of Sex, Damned United, The Good Fight and other projects, the actress prefers to keep her life more private.

The expected baby will be Sheen’s second child, who shares 20-year-old daughter, Lily Mo Sheen, with 45-years actress Kate Beckinsale. After dating for a good eight years, the couple split in 2003. But, they still share a healthy relationship and even spent their last Christmas together with their daughter and friends.

The Underworld actress spoke about co-parenting with Sheen, “I think the thing is, if you both really put your kid’s well-being first and share a sense of humour, you’re sort of halfway there.”

The entire family shares a pretty good sense of humour, and that’s an essential reason for the strong bond that they share – the actor’s humour sense is not hidden, and things, like the below mother-daughter chat between the two, confirms that they are none the less.

Beckinsale often shares their humorous conversations on Insta, which sweeps everyone rolling with laughter.

Michael was also famously linked to 35-year-old Irish comedian and actress, Aisling Bea. Then in 2014, he started dating comedian Sarah Silverman, which lasted three years.

On their split, Sarah wrote, “We just live in different countries & it got hard. Felt we should just tell y' all so u stop askin, 'How's Michael/How's Sarah?

Good Omens tweeted back to Sheen on his expected baby news, “Just don't let the @chattering_nuns deliver your little angel. Congratulations, @michaelsheen! #GoodOmens.”

The would-be parents, Sheen and Lundberg posed for a photograph at the premiere of his Good Omens, on July 16.  The picture was captioned by her, “What an incredible night to be a part of! I’m overwhelmed with pride and couldn’t be happier for Michael and the cast.”

We congratulate the couple and can't wait to meet their new addition!
