It looks as though Kendall Jenner has her mom's blessing when it comes to dating bad boy Chris Brown. Rumor has it that the Kardashian family matriarch Kirs Jenner approves of her daughter dating the controversial singer, despite his poor reputation with women.

According to Star Magazine on Thursday, things might be heating up between Kendall and Brown with many insiders assuming that the two might be taking their relationship to the next level.

An insider said, "Kendall was constantly in the studio when Chris was making music this summer. It's no secret that they've been hooking up for awhile."

What's more, it looks as though mom Kris might be encouraging them to date as well.

The source added, "Any normal mom would be concerned for their child's safety in a situation like this. But Kris is only thinking about the money and fame that can come from it."

While Kris might be okay with her daughter dating the rapper, it looks like big sister Kourtney Kardashian certainly is not.

According to OK! Magazine back in October, Kourtney allegedly gave Kendall a stern warning as far as who she should and shouldn't date, which includes the likes of Chris Brown and Justin Bieber.

A source told the mag, "Kourtney's worried over Kendall's choice in men and can't believe she'd so blatantly steal or even flirt with another girl's guy. She totally tore into her over it, begging her to wake up and stop it right now before she gets an even worse reputation."

Kourtney also reportedly told Kendall to stay away from married men, out of respect for her sister Khloe Kardashian, who was cheated on by her ex-husband Lamar Odom.

The insider added, "Kourtney pointed out that with all the hell Khloe's been through with a cheating husband, Kendall should know better. It just doesn't look good."
