Baby on the way!

Pregnant Sarah Michelle Gellar stepped out in Beverly Hills Friday with her adorable daughter, Charlotte Grace, who turns 3 on Wednesday.

The soon-to-be mother-of-two is expecting a baby boy with husband Freddie Prinze Jr. later this year, a source close to the couple confirmed to Us Weekly

Gellar, 35, flaunted her growing baby bump for photographers while picking up Charlotte from school. The Buffy the Vampire Slayer star dressed casually in a brown dress, jean jacket and sandals. But Gellar did sport a pink cheetah-print cami under her low-cut dress, that coordinated with Charlotte's cheetah-print shirt.

"She and Freddie are thrilled," a friend of the pair, who have been married for ten years, told Us. "They're amazing parents."
