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.

A source told US Weekly: ''She and Freddie are thrilled. They're amazing parents.''

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!''

In an effort to keep the love alive, both insist on spending regular time together.

A second insider added: ''They still have date nights all the time and have a normal life. They both came of age in Hollywood and love working, but their home life is more important to them.''
