A friend close to the family reveals that Ben is reportedly thrilled to finally have a “little sports buddy ... he can’t wait to take his son to baseball games and play catch with him.” So how does Jen feel about this? “She feels like she won’t know what to do,” says the pal. “She’s close to her two sisters, and her instincts were spot-on with the girls. But she never had a brother and doesn’t know the drill.”

The happy couple already have two daughters: Violet, age 5, and Seraphina, age 2. A rep for the actress has yet to confirm the news, so we'll keep you posted!
