One Direction's Harry Styles talked about his past relationships in the band's upcoming documentary and revealed details in specific about his most recent ex-girlfriend, Taylor Swift.

In This Is Us, the 19-year-old United Kingdom native said his time with Swift was not easy. He reportedly referred to his relationship with the 22 singer as "a pain in the arse," according to Daily Star.

Styles also talked about his other ex-girlfriends, though not specifically by name.

"I haven't met a girl yet who I'd want to even think of getting serious with," he said. "I think I've been unlucky in love so far. But then, I haven't met anyone who's made the Earth move for me."

As for what he looks for in a girl, Styles added, "I'm longing to meet someone who really inspires me and makes me really want to spend time with them."

This Is Us is set to release in August 2013. The documentary gives an insight into the band's Take Me Home tour, and their trips to Europe and Japan. Director Morgan Spurlock (Super Size Me) said viewers will see "more shirtless moments than you can imagine."

Swift, 23, talked about her own preferences in an interview with Vanity Fair as she graced the magazine's April 2013 issue. She denied claims of her being "boy-crazy" and said she hopes to find someone who sees really who she is and not the "fictional character" tabloids portray her as.

"If I could find someone who just looked at me like I'm a girl, like a girl they want to be their girlfriend, with all my accomplishments and my criticisms," she said, "without this big cartoon character that most people see me as."
