They have never openly confirmed their relationship but now One Direction's Harry Styles and Caroline Flack have called time on their controversial three-month romance.

The mismatched couple allegedly started dating in October last year after they shared a drunken kiss on a night out.

Despite facing a backlash from fans, because of their 15-year age gap, the pair continued their fun-filled fling.

During their relationship, they avoided being photographed together, and refused to reveal details of their romance.

The 17-year-old singer took to Twitter to confirm he had split with the 32-year-old Xtra Factor host but insisted that the split was a "mutual decision"

Young heartthrob Styles tweeted: "'Please know I didn't "dump" Caroline. This was a mutual decision. She is one of the kindest, sweetest people I know."

However, a source close to the singer told The Mirror that the breakup was due to Styles not wanting to be tied down.

The insider said: "He really likes Caroline and he doesn't want to hurt her. But he doesn't want to be tied down."
