Kim Kardashian is worried about Kendall Jenner dating Harry Styles
Kim Kardashian fears Kendall Jenner will get hurt by 1D singer Harry Styles
Harry Styles was once passionate about Taylor Swift
Taylor Swift believes Harry Styles broke up with her because he wanted to chase other girls
Kim, 33, is said to have flipped when she first heard about 18-year-old Kendall's dates with the One Direction singer, 19.
Our source says: ‘Harry and Kendall have been circling each other since being introduced a few months ago and are finally taking that next step.
'But Kim knows all about being played and fears Kendall will get hurt by the king of heartbreakers.'
It's fair to say Hazza's earned his womanising rep, having been linked to a string of celebs including Xtra Factor host Caroline Flack, 34, supermodel Cara Delevingne, 21, and singer Taylor Swift, 23.
Kim's so worried that she's asked her fiancé Kanye West to drill home how risky dating a pop star can be.
‘Apparently Kanye's been telling Kendall that rock stars can be dogs,' says our source.
When we contacted Kim's reps they denied she'd been meddling in Kendall's love life.
But it isn't just Kim who's apparently giving Kendall aggro!
Harry's ex Taylor Swift has also offered words of warning.
Our source says: ‘Taylor told Kendall how hard Harry pursued her - then broke up with her to chase other girls.'
