The film heartthrob married Brazilian model Camila Alves at their home in Austin, Texas, on Saturday night. For the romantic sunset ceremony Matthew swapped his usual casual shorts and T-shirt for a three-piece black Dolce & Gabbana tuxedo. Camila also looked stunning in a gown handmade by her favourite Brazilian designer and white Stuart Weitzman high heels.

"Matthew looked so handsome, like an Old Hollywood movie star," a guest told People. "And Camila was just glowing and beautiful!"

Reese Witherspoon was amongst the guests to witness the intimate nuptials, which were reportedly kept a secret until the last minute. The actress who stars alongside Matthew in the new movie Mud wore a green dress to cover her growing baby bump.

Matthew and Camila's two young children, Levi and Vida, were also present for the ceremony.

Celebrations took place over three days at the couple's Oak Estate home, with guests staying in luxury tents complete with air conditioning, beds, white fur rugs and outdoor seating.

During the weekend, people lounged in hammocks, played lawn games and sipped chilled beers.

Matthew and Camila got engaged on Christmas Day last year after a five-year relationship.

Matthew's representative has confirmed that Camila will now be officially known as Camila McConaughey. (C) Cover Media
