Awwww, he was just giving her mad props on the release of her new album, Demi! Cute!!
Plus, we're pretty sure Joe is still smitten with his model girlfriend, as they were recently spotted together chilling in NYC.
Maybe it got Joe feeling all nostalgic for the days of Demi!
Cause that would be kind of adorable.
