Sarah Michelle Gellar has given birth to a baby boy.

The Buffy the Vampire Slayer actress and her husband Freddie Prinze Jr. welcomed their second child - a brother for three-year-old daughter Charlotte Grace - last week, and both mother and baby are doing well.

"Sarah Michelle and Freddie Prinze Jr are thrilled to announce that they welcomed a baby son into the world this past week. Mother and baby are doing great. And Charlotte is very excited to be a big sister," a representative told Us Weekly.

A name for the baby is not yet known.

Sarah and Freddie - who have been married for 10 years - were said to have been hoping for a baby boy earlier this year and were glad when a scan proved that to be the case. "Sarah was secretly hoping for a boy. She realizes this will most likely be the last baby she has, so she's so happy she'll have the experience of raising one of each," a source previously said.
