Watch out, Harry Styles: Your new relationship with Taylor Swift might not be for the long haul. The "I Knew You Were Trouble" singer opened up in a new interview about how she can't seem to keep a relationship going for a lengthy amount of time.

"I don't know how to make relationships last," she tells Cosmopolitan UK. "I've never had a really long relationship, so I have no idea what that's like. Wish me luck for the future!"

With that being said, Swift doesn't discriminate when it comes to the men she's dating. From John Mayer and Jake Gyllenhaal to Taylor Lautner and Conor Kennedy -- and now One Direction hottie Styles -- Swift says she tries to chose her beaus based on what's inside.

"I really don't have any rules about dating when it comes to height, age, career choice, anything like that. It doesn't matter," she says. "It's really more about strength of character. When it comes to age I've been all over the map!"

This news hasn't stopped Stylesgate from heating up, though. Swift and her 1D boyfriend have continued their string of dates in NYC, this time packing on the PDA and making out publicly at a friend's birthday party in New York's Crosby Hotel, People reports.
