The Expendables star let the news slip while promoting their new show Brooklyn Nine-Nine on Tv in America on Tuesday (17Sep13).
Asked about his relationship with his co-star, Crews said, "He's getting married this week."
Crews, who will miss the wedding because he's too busy promoting his new comedy series, admits he has had a heart-to-heart chat with Samberg about the sanctity of marriage.
He tells Access Hollywood Live, "I've been married 24 years, so I'm like, 'Dude, be serious, this is real.'"
News of Samberg's engagement to his girlfriend of five years broke in February (13).
