Jessica Alba has become a first-time mother after welcoming a baby girl this weekend, according to reports.

The actress and her husband Cash Warren are celebrating the birth of a baby girl, who was born on yesterday at Los Angeles' Cedars Sinai Medical Center, according to Us Weekly.

The tot's name is unknown, as is the weight of the child.

The Sin City beauty married beau Cash last month in a secret ceremony, failing to invite even close friends and family.

The pair met in 2004 on the set of blockbuster The Fantastic Four.

Alba and Warren recently moved into a $4 million (£2million) mansion in L.A. in preparation of their first child, and Alba admits it is set to be a busy year.

She says: "It's a lot of stress to buy a house, have a baby and get married in six months," she recently told USA Weekend. "It's a lot of life-changing decisions. I'm really, really secure."
