Jennifer's one-time co-star Victor Garber, who officiated their wedding, confirmed the gorgeous 36-year-old is up the duff with a new brother or sister for their two-year-old daughter Violet.
Victor told Us magazine in a taped interview that "yes, she is," when asked if Jen and Ben were expecting another child.
A source told the magazine that Jen is five months pregnant and that the couple are "very happy."
Jen had been hoping for another baby, telling UK Marie Claire in the past that her actress lifestyle is perfect for raising babies.
"We definitely wonder what it would be like to have another - hopefully, knock on wood, someday," she told the magazine before learning of her second pregnancy. "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."
