It seems like Harry Styles and Kendall Jenner's rumored relationship is causing some (more) drama.

Not only is Taylor Swift allegedly pissed about the couple, but Kim Kardashian and Kanye West aren't too happy with the arrangement, either, according to Now Magazine.

As the source tells it, Kardashian is concerned with her younger sister's well-being and is worried about the One Direction singer's reputation with the ladies.

"Kim knows all about being played and fears Kendall will get hurt by the king of heartbreakers," the insider revealed to the UK mag.

While we don't know if Styles is necessarily the heartbreak "king," he has certainly dated his fair share of women in his 19 years, including Swift, the twice-his-age Caroline Flack and model Cara Delevingne. And this hasn't gone unnoticed by Jenner's soon-to-be brother-in-law, Kanye West.

"Apparently Kanye's been telling Kendall that rock stars can be dogs," the source told the magazine. (We guess he would know!)

What do you think of Kendall and Harry's relationship, PopCrushers? Do they make a cute couple, or should they just remain friends?
