Second daughter for Ben Affleck

The couple already have a three-year-old daughter called Violet

US actors Jennifer Garner and Ben Affleck have welcomed the arrival of their second daughter.

The couple's publicists confirmed that Garner "gave birth to a healthy baby girl" but would not provide any additional details.

Garner and Affleck, both 36, began dating in 2004 a year after appearing in the film Daredevil together and married in June 2005.

The actress later gave birth to first daughter Violet in December 2005.

Former Alias star Garner confirmed her second pregnancy in August.

She last appeared on cinema screens in the 2007 hit film Juno.

Affleck made his directorial debut last year with Gone Baby Gone, a film about the disappearance of a child.
