5. Ellie Goulding Leaves Ed Sheeran For One of His Mates

Close friends Niall Horan and Ed Sheeran had a falling out after falling for the same girl. Ellie Goulding, a singer close to both boys, was caught cheating with Horan in 2013. Although Ellie Goulding denies they were ever dating, Ed Sheeran, singer and songwriter, insist that they were dating when One Direction star Niall Horan and Goulding hooked up. He even wrote a song that’s most likely about Goulding/Horan called “Don’t.” Sheeran claims that the pair had sex while they were all staying at the same hotel together, breaking his heart and tearing up his friendship with Horan at the same time. All three of the singers have since reconciled with one another; Sheeran claims he’s totally over it and just “grateful I could get a song out of it.”
