0924_smg_singleThe newest "Buffy" baby is here -- Sarah Michelle Gellar has given birth to a little boy!

Us Weekly is the first to report that the 35-year-old and her handsome hubby Freddie Prinze Jr., 36, are proud new parents.

"Sarah Michelle and Freddie Prinze, Jr. are thrilled to announce that they welcomed a baby son into the world this past week," her rep told the magazine.

"Mother and baby are doing great," the rep added. "And Charlotte is VERY excited to be a big sister."

No other details about the little guy have yet been released.

The couple first met while shooting the 1997 flick "I Know What You Did Last Summer" and have been married since 2002. Their first child, daughter Charlotte Grace, just turned 3 last week.

Baby Prinze is the second "Buffy the Vampire Slayer" baby born in the past several months -- Alyson Hannigan, who played Willow, and her hubby Alexis Densiof, who played Wesley, welcomed their second little girl in May.

Congratulations to the family!
