The country singer - who has dated Hollywood hunks Jake Gyllenhaal, Joe Jonas, Taylor Lautner and John Mayer - claims her showbiz relationships have all ended because her jealous exes couldn`t handle her being more successful than them.

Taylor explained: "I`ve found that men I`ve dated who are in the same business can be really competitive. I`ve found a great group of girlfriends in the same business who aren`t competitive, but a few times guys have started comparing careers and it has been... challenging.

"The last thing I think about when I fall for someone is what they do for a living as I like to get to know that person, but sometimes guys start acting weirdly towards me, especially if I get good news and they get bad... It`s usually downhill from there."

The `We Are Never Ever Getting Back Together` hitmaker is famed for penning lyrics about her ex-boyfriends and she can`t believe anyone would ask her not to put down her feelings in music as they should assume it`s a "waiver" of dating her.

Taylor told You magazine: "It`s mind-blowing how some guys have just handed me inspiration for some of these songs on a plate. Some have said, `Please don`t write about me,` but only when we`re in the process of breaking up.

"If a man dates me, he`s kind of signing a waiver saying he`s cool with me writing songs about him. I write songs about my life: it`s not something I`ve kept secret."

The blonde beauty - who is now dating Conor Kennedy - says she wasn`t always so popular with the boys, however, and struggled to get a date at school.

She admitted: "I was never a boy magnet at school. There was always the girl all the guys liked and wanted to date, but it was never me."
