Nick and Olivia had been dating since August 2013, when they met at the 2013 Miss USA competition.
Rumors of a split have surrounded the former couple recently, especially since the good-looking pair hasn't been seen together since the 2015 Billboard Music Awards on May 17.
But just last week in an interview with ABC News, Nick said that their relationship was going "good." But the "Chains" singer did admit that being in a long-distance relationship was "tough." "Dealing with that is always an interesting thing, but it's all good," he said.
"We're both busy, and young, and enjoying life, so, it's going well." Last November, he revealed that his song "Jealous" was actually about Olivia.
The two attended many celebrity events together, as well as the 2014 Miss Universe pageant, where he performed and at one point, stepped off the stage into the audience and sang to the beauty queen on one knee.
