Wedding bells for pregnant Alba

Alba recently said Warren would make "the best" father

Actress Jessica Alba has married her boyfriend Cash Warren in a private ceremony, her publicist has confirmed.

The couple got engaged in December after the Sin City star announced she was expecting a child, due this summer.

Alba, 27, has been dating Warren since autumn 2004. The pair met on the set of The Fantastic Four, on which Warren, 31, worked as a director's assistant.

The actress, who recently starred in thrillers Awake and The Eye, will next be seen in comedy The Love Guru.

The California native first gained fame as a genetically enhanced fugitive on TV series Dark Angel.

'Dream come true'

According to some reports, Monday's wedding took even their families by surprise.

"My sister? I'm going to have to call her!" Alba's younger brother Josh said when magazine Us Weekly contacted him with the news.

In an interview to promote The Eye in January, the actress said Warren would be "the best" father.

"It's kind of a dream come true," she said as she showed off her engagement ring.
