Although his wife of two years, Anna Paquin, is expecting their first child together, Stephen Moyer has already proven his parenting skills.

Opening up to Us Weekly at the L.A. premiere of Marley Monday night, the actor's True Blood costar, Janina Gavankar, gushed about what a great father Moyer, 42, is to his two children from previous relationships: son Billy (born in 2000) and daughter Lilac (born in 2002).

Unlike his "brooding" character Billy, "Stephen…is such a proud father, and so light-hearted and shiny," Gavankar, 31, told Us. After mentioning that Moyer's son Billy recently spent some time on set, the actress added that, thanks to his father's influence, the tween is "such a sweetheart."

In 2010, Paquin, 29, had previously talked about wanting to put off having children with her husband until "the time's right." Two years later, the actress and her love now seem ready to start a family of their own--a rep for Moyer confirmed to Us Tuesday night that Paquin is indeed expecting.
