Theirs was a romance to be jealous of, but after two years together the singer and the former Miss Universe decided to end their relationship in June. "Your heart just breaks, that's all," Culpo captioned an Instagram photo of palm trees against a sunset. "Heartbreak is hard but you find more and more things to be grateful for every day." For his part, Jonas told Extra's Mario Lopez that although the split has been tough, he wishes his ex the best.
