Actress Jessica Alba, who married her longtime boyfriend Cash Warren three weeks ago, has given birth to a baby girl, according to US Weekly magazine. The same source reported the 27-year-old gave birth at the Cedars-Sinai Medical Centre in Los Angeles, California, over the weekend.

The magazine’s insider told that “Alba’s father was overheard saying ‘she’s beautiful,’ while Warren was spotted carrying food into the maternity ward Sunday.”

One of the “sexiest” women in the world – she was No.1 to FHM readers last year and reached No.3 this year – announced last December that she was pregnant. The two met on the set of “The Fantastic Four” in 2004, where Warren worked as director’s assistant. The 27-year old Jessica Alba and the 29-year old Cash Warren have been since then together, forming a happy couple.

When asked about her pregnancy, Alba said it is “quite a blessing and it couldn’t be more perfect timing.” She compared the experience with that of a roller coaster of emotions, saying pregnancy is not something she is used to. “Anything could make me incredibly angry or break down crying,” the actress told the TV show “Extra.” Her only fear about mommyhood was breastfeeding. She admitted she was “excited for motherhood,” although she didn’t plan her pregnancy.   

Alba’s most recent appearances have been the thriller “Awake,” the romantic comedy “Good Luck Chuck” and “The Ten.” Alba rose to fame with the television series “Dark Angel” (2000-2002). She later appeared in various films such as “Honey” (2003), “Sin City” (2005), “Fantastic Four” (2005), “Into the Blue” (2005), “Fantastic Four: Rise of the Silver Surfer” (2007) and “Good Luck Chuck” (2007).

The couple exchanged vows during a low-key ceremony in Beverly Hills courthouse on May 19.
