Freddie Prinze Jr.'s love (sporting an ace bandage on her right wrist) toted the couple's three-year-old daughter, Charlotte, and rocked a black sheer blouse, skinny cargo pants and black leather booties for her afternoon out.

On September 24, the former Buffy star's rep confirmed to Us Weekly she had given birth to a baby boy. (The couple have yet to announce their son's name.) Since welcoming their new addition, the second-time parents are "so happy," an insider close to the pair tells Us.

"He loves it," she told Us. "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!'"

Added Gellar, "He and Charlotte have too much fun. I'm jealous!"
