Selena Gomez and Demi Lovato
These Disney princesses have a pretty long history of breakups and makeups — to be honest, we don't even know where to start. Let's see: Demi Lovato and Selena Gomez first met on the set of Barney & Friends when they were little girls. The two grew up to both star on Disney channel shows and become huge performers, but it seems as though the girls grew apart somewhere along the way. Demi spoke out about their rift in 2010, saying: "We’re both busy, and I wish the best for her. True friends don't let their friends or family be mean to you. If you can’t trust somebody, you can’t be friends with them." Ouch.
Selena responded later that year, explaining that she and Demi "had our distance, and we've had our moments, but she's one person that I will always love, and she'll always have a place in my heart." In May 2013, Demi hinted at a reconciliation between the two on MTV News: "Now we are in a place where I think we realized that life is so short and that when you have people in your life that love you so much then, you should just always be around them." Their on-again status was confirmed in September 2015 when Demi shared an Instagram photo of the two on a night out, writing, "Look at how #coolforthesummer we are.. Friends for years, #sameoldlove."
