Cash Warren and Jessica Alba 

Details have emerged about Jessica Alba’s quickie wedding to her baby daddy Cash Warren.

According to a source, they were married in the Beverly Hills courthouse’s ceremony room under an arch of green silk foliage and white flowers. That sounds a bit tacky to us.  They were casually dressed, with Alba wearing a long blue dress and her hair back in a ponytail.

“She looked happy but nervous,” the source says.

Warren, in a white shirt and brown pants, arrived with Alba at about 11:30 a.m. on Monday, applied for a marriage license and waited about 40 minutes for the paperwork to be processed before a staff member from the courthouse married them, the source says.

Nobody else attended the wedding.   

Alba, 27, is expecting a daughter with Warren, 31, this summer. The couple met while filming Fantastic Four in 2004 and were engaged last December.
