Matt Damon [1] gave his thoughtful two cents on marriage when Entertainment Tonight asked how his childhood friend Ben Affleck [2] is doing in the wake of his split from Jennifer Garner [3]. "He's good," Matt said, adding, "I think marriage is insane. Like, it's a crazy idea, but I love being married to my wife, you know what I mean? So I wouldn't tell anybody else anything about their relationship." The actor sweetly gushed about his other half, saying, "I'm lucky I found my wife. And I guess, maybe, if there's any secret, it's that: it's to feel lucky." Matt and his wife, Luciana Barroso, will celebrate their 10th wedding anniversary in December, and they recently stepped out for a sweet date night [4] together. Check out the trailer for Matt's new movie The Martian [5], and then see Matt and Ben's cute red carpet appearance [6] from earlier this month.
