Matthew McConaughey and Camila Alves sealed the deal. They are now husband and wife!

US Weekly magazine reports that the Hollywood heartthrob and the Brazilian beauty had quite the emotional ceremony on Sunday.

"There were no groomsmen or bridesmaids," a guest told the magazine. “There were two preachers, [a pastor of a local church] and a monk. They switched off saying remarks."

The lovebirds also made sure to keep their vows completely private.

"They whispered them in each other's ears. No one knew what they said," the source added.  "Whatever they said was very emotional. [Camila] was tearing up."

The guests were also extremely emotional, according to the source who said “there were many tears around.”

"There was a lot of clapping and everyone was happy," the sources continued, adding that "Matthew loves her and there is no doubt about that."

McConaughey popped the question over the Christmas holiday last year and then took to Twitter to tell his fans about his new fiancée.

"Just asked Camila to marry me, #MerryChristmas," McConaughey posted on his Twitter account, followed by a link that led to a photo of the two kissing.

McConaughey, 42, shares two children with Alves, Levi, 3 and Vida, 2. The actor and Alves have been an item since 2006, The New York Daily News reports.

The stunning Alves is the host of Bravo's reality show "Shear Genius," which pits hairdressers against each other.

McConaughey told GQ Magazine a few months ago that Alves is the woman he wants to "make a family with" and live his "life out together".

"I always wanted to be a father," McConaughey told People Magazine in 2008. "It just took the right woman and the right time to make it happen."
