The couple announced the happy news on social media.
Congrats to Guy Pearce and Carice van Houten, who have welcomed a baby boy!
Pearce tweeted the happy news on Monday morning, sharing “A cute little package arrived and told us his name's Monte Pearce. We think we're gonna keep him. Placenta smoothie anyone?”
Van Houten, who stars as the “Red Woman” Melisandre on Game of Thrones, retweeted Pearce’s announcement, adding a series of emoji, including a baby, roller coaster, martini, and of course, heart eyes for their new bundle of joy.

The pair announced they were expecting back in March, with a few good-natured tweets about van Houten’s slightly sinister GoT character.
“Ok. I'm ready for your shadowbaby jokes,” the 39-year-old actress teased fans on Twitter.
“Nothing like the prospect of a shadowbaby to change your mind about becoming a Father!!” Pearce, 48, replied, before sharing sincere thanks to fans for all the well wishes.
Baby Monte is the first child for both stars. Pearce was previously married to psychologist Kate Mestitz from 1997-2015.
