Prime Hollywood actor Matthew McConaughey is now engaged to his longtime girlfriend and the mother of his two children Camila Alves.

Matthew McConaughey proposed to the Brazilian model and performer on Christmas Day. A perfect Christmas present isn't it? The actor shared the good news to all of his fans via Twitter. " Just asked Camila to marry me, Merry Christmas," he announced. The actor also shared a romantic photo in his WhoSay account wherein the couple shared a sweet kiss by the Christmas tree.

The two met way back in 2006. The couple has two children, son Levi Alves McConaughey - who was born in 2008 - and daughter Vida Alves McConaughey - who was born in 2010 - together.

The two lived between Austin and Malibu. Matthew spent years living in an RV in which he professed his love for living a simple life.

The proposal may come as a surprise for Camila who recently said that they are in no rush to get married. "We've got no plans right now," she told OK magazine. "We're good as we are right now. We're happy and good as we are. So far, so good!," the model quickly added.

Matthew McConaughey recently starred in the film "Killer Joe" with Emile Hirsch. The movie also stars Juno Temple, Thomas Haden Church, Gina Gershon, and is directed by "Exorcist" maestro William Friedkin.

It tells the story of 22-year-old drug dealer Chris (Hirsch) who has to come up with six thousand dollars quick or he's dead after his mother steals his stash. Desperate, he turns to Killer Joe (McConaughey) when he finds out that his mother's life insurance policy is worth $50,000.
