Jessica Alba was “taken.” The 27-year-old actress married her longtime boyfriend Cash Warren on Monday. The couple, who have a baby girl on the way, became engaged in late December.

They met on the set of the “The Fantastic Four” in 2005, where Warren worked as director’s assistant.

Jessica Alba, 27, and Cash Warren, 31, exchanged vows during a low-key ceremony in a Beverly Hills courthouse.

Their wedding was a quiet affair. Under an arch of green silk foliage and white flowers, the lovers were casually dressed; Jess wore a long blue dress and her hair back in a ponytail and Cash wore a white shirt and brown pants.

The ceremony was discrete and so it was their first meeting, when Alba said jokingly she didn’t felt that Warren was her “soulmate,” but thought “Oh, I’m going to know you for the rest of my life.”

“She looked happy but nervous,” a source said, quoted by People.com.

In an April interview Alba said she didn’t plan her pregnancy, but she admitted she was “excited for motherhood. “I think it's the best thing in the world that could have ever happened,” the actress said, adding that she wanted to have a baby before the age of 31.

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). Alba's most recent appearances have been the thriller “Awake,” the romantic comedy “Good Luck Chuck” and “The Ten.”

Jessica Alba is considered one of the “sexiest” women in the world. She was No. 1 to FHM readers last year and reached No.3 this year.
