Affleck and Garner expecting second child

Ben Affleck and Jennifer Garner are expecting their second child, confirms actor Victor Garber.

Earlier this month, reports surfaced the actress was pregnant - but Affleck's spokesperson refused to confirm or deny the reports.

Now Garner's former Alias co-star Garber - who officiated the couple's 2005 wedding - has confirmed the news, saying: "Yes, she is".

A source tells Usmagazine.com that Garner is already five months into her pregnancy.

The insider adds: "She and Ben are still deciding whether they'll ask the sex of the child."

The pair welcomed daughter Violet in December 2005.
