Taylor Swift has admitted she does not understand how to make her relationships last.
The singer, 22, who is currently dating One Direction hunk Harry Styles, has previously been linked with Conor Kennedy, Taylor Lautner, Jake Gyllenhaal and John Mayer.
Taylor has lamented the fact none of her romances have worked out but she is hoping her love luck changes in the future.
"I don't understand how to make relationships last," she said.
"I've never had a really long relationship, so I have no idea what that's like. Wish me luck for the future."
The We Are Never Ever Getting Back Together singer also admitted she doesn't have a particular physical type when it comes to her boyfriends as she finds "strength of character" the most attractive quality.
"I really don't have any rules about dating when it comes to height, age, career choice, anything like that," she said in an interview with Britain's Cosmopolitan magazine.
"It doesn't matter. It's really more about strength of character.
"When it comes to age, I've been all over the map."
And the blonde beauty says the best relationship advice she ever received came from talk show host Jay Leno, who told her to find someone who made her want to be better.
"Jay Leno told me, 'It's easy. Just marry your conscience. Marry the one who makes you want to be a better person'," she explained.
