Sarah Michelle Gellar and husband Freddie Prinze Jr. welcomed a baby boy last week.

“They are thrilled to announce the news,” their rep tells Access Hollywood. “Mother and baby are doing great.”

So how does the couple feel about baby # 2? “They are thrilled that Charlotte has a little brother,” a source told PEOPLE. “They love their little girl more than anything in the world and know that love will only multiply.”

This is the second baby for the couple who got married back in 2002. The new baby joins their older daughter Charlotte Grace, 3.

Congratulations!
