Jennifer Garner and husband Ben Affleck are expecting another baby, Garner’s former "Alias" co-star Victor Garber told Usmagazine.com

"Yes, she is," Garber, who currently stars on ABC's "Eli Stone," told Us when asked if recent speculation was true that the couple is expecting (Garber officiated the couple's 2005 wedding).

A source also told Usmagazine.com, "She is five months pregnant. They are very happy."

Garner, 36, and Affleck, 35, are parents to 2-year-old daughter Violet.

Garner hinted in October that she wanted to have another child.

"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."
