Jessica Alba and her husband Cash Warren have welcomed a baby girl called Honor Marie Warren.

The Sin City star's representative Brad Cafarelli confirmed to People that Alba gave birth to the tot on Saturday, and not Sunday as previous reports had claimed.

Honor was born at Los Angeles' Cedars Sinai Medical Center, which has also seen the births of Halle Berry’s daughter Nahla, Christina Aguilera’s son Max and Nicole Richie’s daughter Harlow.

It is the first child for the actress and new husband Cash Warren, who wed in a low-key ceremony at Beverly Hills Courthouse last month.
