The 38-year-old actor and former `Beverly Hills 90210` star - who already have 16-month-old daughter Billie Beatrice - are thrilled with the news that they will welcome another child into their family later this year. A source told Life & Style magazine: "She`s glowing -- and so happy. They wanted to add another child to their family, and now they`ve got that! They`re in a real good place." A spokesperson for the couple confirmed they are expecting another baby, but did not say when the new arrival is due. `Grey`s Anatomy` star Eric - who married Rebecca in 2004 - recently admitted he finds his wife even more attractive since she gave birth to Billie. He said: "I don`t know if there`s any change more significant that a human being can make than that of a woman becoming a mother. There`s no change more dramatic. "You know, I`m a hundred times more attracted to her now and I love her exponentially more than I did before. It`s just great to see her be a mother." Eric also spoke of how much he enjoys taking his daughter to the park and seeing how much she enjoys the experience. He said: "I like watching her laugh. Seeing this kid laugh when you put her on the swing, or slide down the slide with her, it`s just. She owns me."
