Sarah Michelle Geller and hubby Freddie Prinze Jr. are celebrating the latest addition to their family, a little boy!

On Monday, a rep for the couple revealed to People that Geller “had a baby boy last week in Los Angeles.” There were no details on the date, but the actress was spotted taking the couple’s three-year-old daughter Charlotte to school on Wednesday, looking very pregnant.

The rep also told Access Hollywood that Geller and Prinze “are thrilled to announce” the happy news and that the “mother and baby are doing great.”

The sex of the new baby was no surprise, since a friend of Geller revealed to People back in July, “They are thrilled that Charlotte [has] a little brother. They love their little girl more than anything in the world and know that love will only multiply.”

So what will Geller and Prinze name the little one? There’s nothing official yet, but Freddie Prinze III has a nice ring to it!

Congrats to Sarah Michelle Geller, Freddie Prinze Jr., Charlotte and the new arrival!
