Joe Jonas broke Demi Lovato's heart when they split in 2010, but now the former couple are incredibly close friends. Surprisingly, it's all because of her boyfriend, Wilmer Valderrama!

"Wilmer is one of the most incredible people on the planet," she said during an interview with Entertainment Tonight. "I've stayed friends with Joe throughout the years and, what's funny, is it was actually Wilmer's idea."

The "Really Don't Care" singer has such a good relationship with all the Jonas Brothers now, but we had no clue it was because of her guy! Wilmer and Demi are such a cute couple. And the fact that he wanted her to be friends with Joe? Even better.

Do you think Dilmer is the cutest couple ever? Is it sweet that he encouraged her to be friend with her ex? Tell us in the comments!
