Matthew McConaughey and Camila Alves whispered their wedding vows to one another.
The couple - who married at their Texas home on Saturday in a sunset ceremony - chose to keep their sentiments private but the 42-year-old actor's words made the Brazilian beauty cry.
A source said: "They whispered them in each other's ears. No one knew what they said. Whatever they said was very emotional. [Camila] was tearing up."
The couple shunned wedding traditions such as having the 'Bridal March' played, being joined by groomsmen and bridesmaids and had two preachers conducting the ceremony.
The guest explained to Us Magazine.com: "There were no groomsmen or bridesmaids. And there were two preachers, [a pastor of a local church] and a monk. They switched off saying remarks."
Though they did not have a traditional ceremony, the couple - who have son Levi, three, and daughter Vida, two, together - donned classic wedding attire, with the groom wearing a three-piece black Dolce & Gabbana tuxedo, and his 29-year-old bride in a handmade gown created by one of her favourite Brazilian designers.
A guest told People magazine: "Matthew looked so handsome, like an Old Hollywood movie star. And Camila was just glowing and beautiful!"
The weddings guests joined the couple for the weekend, sleeping in luxury tents put up in the grounds of the property, and enjoyed a low-key celebration that included playing lawn games such as beanbag and ring toss, as well as being served beer while lounging in hammocks.
