Carice van Houten is a mom! The Game of Thrones [1] actress and her boyfriend, actor Guy Pearce, welcomed a son named Monte [2] on Monday in Amsterdam, where she's originally from. Guy joked about the news on Twitter [3], writing, "A cute little package arrived and told us his name's Monte Pearce. We think we're gonna keep him. Placenta smoothie anyone? @caricevhouten" (Carice responded with a flurry of new mom-themed emoji [4]). Although it's unclear when Guy and Carice officially started dating, the pair was spotted out and about a few times over the last few months, and announced they were expecting their first child together [5] in March. Since then, they've had a blast joking about Carice's pregnancy on social media, especially when it concerns references to Carice's character on Game of Thrones, Melisandre:

Ok. I'm ready for your shadowbaby jokes.

Congratulations to the new parents! Hopefully all of the other celebrities expecting babies this year [9] will have such adorable announcements.
