Sarah Michelle Gellar and husband Freddie Prinze, Jr. are expecting their second child.

The couple - who met on the set of 1997 horror film I Know What You Did Last Summer and started dating three years later - have reportedly decided to give daughter Charlotte Grace, two, a little brother or sister.

"She and Freddie are thrilled. They're amazing parents," a source told US Weekly.

The actors tied the knot in Mexico in September 2002, and admit they often fight about who gets to stay at home with their little girl, and who has to go to work. Sarah, 35, who recently returned to the screen in drama series Ringer, said, "We fight over who gets to stay home. You'd think it would be the opposite, that the parents would be like, 'No, I'll go to work!' but he's like, 'You stayed home for two years! It's my turn!' He and Charlotte have too much fun. I'm jealous!"
