Joe Jonas and Demi Lovato became friends on the set of "Camp Rock" in 2008. By the time the sequel rolled around in September 2010, they were a couple. Their public relationship was short lived, however, and they only dated until the end of 2010.
They have both since moved on. Jonas married Sophie Turner in May 2019, and they had their first baby together in July 2020. Lovato has been linked to Wilmer Valderrama, Noah Cyrus, and more.
However, Jonas and Lovato still seem to be on good terms. Lovato went on tour with Jonas's brother, Nick, in 2016. Then, in October 2021, Lovato and Jonas reunited at a Halloween party, even snapping a selfie together.
