Joe Jonas & Demi Lovato Get Nostalgic for '#7YearsOfCampRock'


#7YearsOfCampRock started trending on Twitter Saturday, and the film's biggest stars weren't immune to the social media nostalgia.

Joe Jonas
jumped right in with both appreciation and shock that it's been so long since the Disney Channel Original Movie premiered, even pulling his co-star, ex-girlfriend Demi Lovato, into the conversation. "Thank you for all the fans who still watch and love the film," the 25-year-old singer wrote. "#ifeeloldnow what about you @ddlovato?"

Demi's response was pretty perfect:

After teasing Joe, the 22-year-old singer also shared her feelings about that little DCOM, including a little shout out to her most famous song from the flick, "This is me." "How incredible," she tweeted. "7 years since my life changed and my dreams came true."

Demi and Joe only dated for about a month during their Disney days in 2010. While Demi was mad at him at first, they're now on very friendly terms. In fact, she's said that all three Jonas guys are "like brothers," and Joe even made a surprise appearance at Demi's Staples Center show in Los Angeles last September. Relive their 2014 mini-reunion, where they sang "This Is Me" for a stoked crowd, below:
