Jennifer Garner: Pregnant!

Jennifer Garner has another bun in the oven.

When asked if his former Alias co-star was pregnant,Victor Garber said: "Yes, she is."

Another source, meanwhile, told Us Weekly that the Juno star "is five months pregnant" and that she and husband Ben Affleck "are very happy."

In October, Garner wasn't shy about admitting that she wanted to give daughter Violet a brother or sister.

"We definitely wonder what it would be like to have another - hopefully, knock on wood, someday," Garner told Britain's Marie Claire. "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."
