JESSICA ALBA was so desperate to keep her nuptials private on Monday (19May08), she didn't invite any guests.

News of the wedding leaked out on Tuesday (20May08), a day after the pregnant star and her fiance Cash Warren had exchanged vows at Beverly Hills Courthouse.

Alba reportedly wore a long blue dress for the ceremony.

According to People.com, the website which broke the news of the union, the newlyweds applied for a marriage license on Monday morning and waited for the paperwork to be processed before a staff member from the courthouse married them.

The couple announced its engagement in December (07), shortly after Alba revealed she was pregnant.
