Reality TV star Khloe Kardashian is reportedly worried about her boyfriend rapper French Montana's regular partying.

Khloe is said to be worried that Montana's social life has begun to threaten their four-month relationship, reports femalefirst.co.uk.

"She's starting to wake up (to the situation)," said a source.

Khloe's mother Kris Jenner is also annoyed with the rapper's behaviour.

"(Kris) thinks (Khloe) needs to be single because she worries that Khloe just got out of a marriage," said a source.

However, Khloe, who began dating French in April after being introduced through a mutual friend, recently defended her new relationship.

"People are gonna comment no matter what. If I dated the most clean-cut, perfect guy, they're gonna comment. So, if I'm having fun and dating this kid, they're not f*****g him, so why should they care?" she said previously.
