Does Taylor Swift have a 'Dating Demands' list? [RUMORS]: How did Harry Styles, John Mayer and her other ex-boyfriends compare to this checklist?

According to a new rumor, Taylor Swift has a checklist she likes to go through when considering dating a new boyfriend. Though this is pretty much commonplace for anyone (admit it, you have a "list" as well!), we're all a bit curious to see how her past relationships have lived up to this alleged list!

"She's all about finding a new boyfriend but she doesn't want just any guy, she wants the perfect guy," an unnamed source told HollywoodLife.com. "She's made a really detailed list of what she wants and it's so intense, there aren't many guys out there that can live up to it."

We all know some of Taylor's exes, so apparently these heartthrobs made it past this checklist.

"She wants someone on her level when it comes to their career, plus, they have to be hot - like leading man hot. And she would love a guy that can speak at least two languages," the insider explained. "There are simple things on the list too. She wants a guy that has at least one sister because she thinks it will make him a better boyfriend. He has to have a good relationship with his parents, especially his mom, but he can't be a mama's boy. Like I said, it is very detailed and it goes on and on. Her friends think she needs to chill. They think being so picky is just going to keep her single."

This source certainly likes to think he or she knows a lot about a personal "romance checklist" of one of the biggest pop stars in the world, don't you think? What do you think of this new rumor?
