The actress has welcomed a baby boy with husband Freddie Prinze Jr., a rep confirms to The Hollywood Reporter. The news was first reported by Us Weekly.

The newborn is the second child for the couple. Daughter Charlotte, 3, is "VERY excited to be a big sister," said the rep.

Gellar, 35, and Prinze, 36, met in 1997 on the set of I Know What You Did Last Summer. They wed in Mexico on Sept. 1, 2002, in a ceremony officiated by Adam Shankman. The couple later co-starred once again in the 2002 film Scooby-Doo and its 2004 sequel, Scooby-Doo 2: Monsters Unleashed.

Gellar most recently starred on the CW drama Ringer, which was canceled after its first season. In the series, Gellar played twin sisters.
