'I Knew You Were Trouble' superstar Taylor Swift has revealed that while there's nothing romantic going on between herself and tour buddy Ed Sheeran, he has given her some fantastic advice on love and dating since they've been on the road together. 

She explained to InStyle magazine that they have grown very close and often talk about personal things, which led Sheeran to give her some words of wisdom about attraction and relationships:

"I think that you can love people without it being the great love. Ed [Sheeran] said something that really resonated with me. He says there are different kinds of love. There’s physical attraction, mental attraction, and emotional attraction - there’s also comfort and obsession."

"You need to have all of those things in one person. You have to mentally respect them, be physically attracted, and have a comfort level. You’re obsessed with them, yet you also know they’re going to stay. I’ve never had that in one person."

In the same interview, Swift opened up about her apparent love for bad boys and joked that it's not healthy to keep going after the wrong guy: "My friends tease me about the fact that if someone seems bad or shady or like they have a secret, I find them incredibly interesting."
