File this one under friendships we didn't see coming.

50 Cent is the king of odd collabs (he was rumored to be dating comedian Chelsea Handler and was in talks to do a duet with Bette Midler last year), and now he can add one more to his list - Goldie Hawn!

"I had lunch with Goldie Hawn she is [a] complete sweetheart," 50 Tweeted.

We can't imagine what the two had to talk about, but it looks like they had a great time!
