The couple married in Beverly Hills courthouse’s ceremony room under an arch of green silk foliage and white flowers. They dressed casually for the private service, with Jessica wearing a simple long blue dress and Cash in a white shirt and brown trousers. No guests attended the event.

According to a source at the courthouse, the couple arrived around 11:30am and spent around 40 minutes completing paperwork to acquire a marriage license before the ceremony could go ahead.

The source added that Jessica “looked happy but nervous” on her way into the ceremony.

The pair got engaged late last year shortly after announcing Jessica’s pregnancy. The baby, their first, is due next month.
