Matthew McConaughey is engaged!

Matthew McConaughey (42) is engaged to long-time girlfriend, Brazilian model Camila Alves (28)! He popped the question on Christmas day. Aww, romantic!

Matthew and Camila started dating in 2006. In 2007 they went public with their relationship. And at 8:47 last Sunday evening, Christmas, Matthew came out on Twitter to say they were engaged. "Just asked camila to marry me," he tweeted, "#MerryChristmas." Merry Christmas, indeed!

Matthew finished the tweet off with a link to this photo on his WhoSay account....

Matthew and Camila have two adorable children together — Levi (3) and Vida (almost 2). Congratulations to the family!

(And, no, I'm not sure what's up with Matthew McConaughey's new buzz cut.... Yea? Or nay?)

Love!
