Taylor Swift says her next boyfriend will have to compete with coffee for her love.

She said: "Coffee's a big part of my life. Skinny caramel lattes are a daily thing that I get excited about and I never stop being excited about.

"So if I could just find one person who I felt that way about--the way I feel about coffee--then I think I'd be in a content relationship."

The blonde beauty, who also previously dated Taylor Lautner, Jake Gyllenhaal and John Mayer, admits she doesn't know a lot of love and no longer believes that finding her "happily ever after" is simple.

She told the December/January issue of Lucky magazine: "I think that no matter what you find in terms of happiness and compatibility, there's always going to be a struggle attached to it. I used to believe that you find the one and that's it: Nothing's difficult after that.

"But then again, I know nothing now. I know legitimately nothing about lasting relationship experiences because I don't have them."

Taylor has adapted to life in the limelight and thinks celebrities who complain about their lives are "irritating."

She said: "I wanted to make music. I didn't know that came with this expectation that your whole life is owned by the general public and everything you do is dissected, scrutinised and questioned. Because [people with] a sunny outlook are a lot easier to deal with, be around, befriend and handle than people who are bitter about it. People who are, like, complaining about the life of being a celebrity. It's a little irritating."
