Niall Horan and Melissa Anne Whitelaw may have called their three-month-long relationship quits! The One Direction singer was first linked to the Australian student in February, and the rumors only intensified after they were spotted cavorting around London together. However, according to The Sun, they ended their romantic relationship because of long-distance.

“Niall and Melissa did well to keep their romance low-profile during their time together. They were really close and had fun whenever they went out together,” their source said.

“But realistically they always knew it was going to be tough, keeping a relationship going with such distance between them.”

They never addressed the relationship rumors, so we don’t know what was really going on between them, but we would understand why they’d call it quits. While they were definitely cute together, his crazy On the Road Again touring schedule probably made it hard for them to see each other. At least it sounds like they didn’t end things on bad terms!
