'Ben Affleck & Jennifer Garner Expecting Second Child'

Ben Affleck and Jennifer Garner are set to welcome a second child, according to reports.

The couple, who have recently been subjected to split rumours, welcomed their two-year-old daughter Violet in December 2005.

And a report in the National Enquirer states they are now expecting a second addition to their brood with the Juno actress set to give birth next year.

A source tells the tabloid: "A few days before the Fourth of July, Jen began calling close pals with the news that she was pregnant again. Jen said she's three months along - and she and Ben are 'ecstatic'."

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

Affleck and Garner wed in June 2005 after meeting on the set of 2003 film Daredevil.
