The Buffy the Vampire Slayer star and husband Freddie Prinze Jr are reportedly expanding their family.

A friend of the pair tells Us Weekly, ""She and Freddie are thrilled. They're amazing parents.""

They first met on the set of 1997 horror film I Know What You Did Last Summer, and began dating three years later. They walked down the aisle in 2002 and welcomed daughter Charlotte Grace in 2009.
