Which Ex Did Demi Lovato Say She Will NEVER Date Again?

Demi Lovato may be currently single for now, but she has been known to strike up an old flame once or twice before! The 19-year-old inspirational entertainer was spotted rekindling her flame with ex Wilmer Valderrama last Halloween and even attended her good friend Tiffany Thornton's wedding with him. She's also had a number of high profile relationships with a few celebs. Which ex is Demi sure of NEVER dating again? None other than notorious heartbreaker Joe Jonas! 

Demi and Joe have been working together on a shoot (along with Pretty Little Liars actor Tyler Blackburn) to film promos for the Acuvue 1 Day Starts Today contest. 

Demi told Us Weekly about their reunion: “We’ve been really good friends for so long. So it’s been cool hanging out with him again” but added that "nothing romantic" was going on between them.
