Jennifer Garner and Ben Affleck are expecting their second child.

The couple — who already have a two-year-old daughter Violet — will soon be adding to their family, revealed Garner’s former ‘Alias’ co-star Victor Garber.

When Garber — who officiated Affleck and Garner’s wedding in 2005 — was asked if the actress is pregnant, he replied: “Yes, she is.”

A source close to the couple told Us Weekly magazine: “Jennifer is five months pregnant. They are both very happy.”

Garner (36) recently hinted she and Affleck were planning to further extend their brood.

She said: “We definitely wonder what it would be like to have another - hopefully, knock on wood, someday.

“My job is great to have as a mom. I get to take breaks and then work in a really concentrated way. During that concentrated time, it sucks, but whatever.”

The ’13 Going On 30’ actress also revealed Affleck (35) is a fantastic father to Violet, adding: “You know how as a kid you picture yourself with a tall, handsome husband, and you imagine him cuddling your baby? Ben is like that, like, on crack!

“Violet prefers him to anyone. He's a teddy bear of a guy. Nothing makes me happier than to see the two of them together and her little hands on his face. He has a prevailing calm. Of course, he has the benefit of sleep!”
