Actress and Cash Warren said, 'I do,' in a Beverly Hills courthouse

Jessica Alba has been very public about her pregnancy, but was sneaky about her marriage.

The expectant actress and Cash Warren, the father of her unborn child, tied the knot away from the glare of paparazzi flashbulbs on Monday (May 19), reports People.

Rep Brad Cafarelli confirmed the marriage, although an unnamed inside source gave more details about the quiet ceremony, which took place at the Beverly Hills courthouse's ceremony room. Both bride and groom were dressed casually, Alba in a long blue dress and ponytail, instead of traditional wedding attire.

The couple applied for a marriage license around 11:30 a.m. and waited about 40 minutes for the paperwork processing before they were married. Alba reportedly looked "happy but nervous."

Alba, 27, and Warren, whose age has been reported as 29 or 31, first met on the set of "Fantastic Four," on which he was a director's assistant. They've been dating on and off since 2004 and finally got engaged last December shortly after they confirmed that they're expecting their first child together.

The baby is expected any day now. Also up for Alba is her appearance opposite Mike Myers in "The Love Guru," hitting theaters on June 20.
