Joe Jonas and Demi Lovato are dating -- though it took 'em a little while to finally admit they had feelings for each other.
Jemi was on Ryan Seacrest's KIIS FM radio show today, where Demi said "I think being best friends for a while, over time, feelings grow and, as much as I wanted to deny it, the feelings were always there."
The two met filming 2007's "Camp Rock" -- and just filmed a sequel.
