Jennifer Garner, who last appeared on screen as an adoptive mother in the teenage-pregnancy comedy “Juno,” is said to be expecting her second real-life baby with husband and onetime co-star Ben Affleck.

There’s no official word from either star’s publicists on recent online gossip about a Garner pregnancy, which has been fueled by recent photos of the actress in loose-fitting tops. But Usmagazine.com reports that her close friend and former “Alias” co-star, Victor Garber, confirmed that Garner is with child. And the magazine quotes an unnamed source as saying, “She is five months pregnant. They are very happy.”

Garner, 36, and Affleck, 35, who battled each other on screen in the 2003 superhero action film “Daredevil,” are parents of a 2-year-old daughter, Violet.  The Hollywood couple announced her first pregnancy and their marriage simultaneously in June 2005. Her pregnancy ultimately was written into the story line of the character she played on the ABC espionage thriller “Alias.”

Garner, who recently appeared on Broadway in a production of “Cyrano de Bergerac,” was quoted last fall in the British magazine Marie Claire as saying she looked forward to having a second child. “We definitely wonder what it would be like to have another — hopefully, knock on wood, someday,” she said then. “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.”
