Kendall Jenner is "game for anything" with Chris Brown.

A source revealed: "Kendall has thought Chris was hot for years now and has always idolised him.

"Kendall conveniently latches on to whomever can make her more famous and she is game for anything that will get her the most exposure."

However, it won't be plain sailing for the 19-year-old television personality as Chris reportedly sees her as a "little girl".

The source continued: "Chris looks at her like a little girl but she does everything to make herself appear to be a woman.”

Kendall is also keen to keep her new beau from her family, especially her sisters.

The source shared: "Kendall tells her sisters that they are not hooking up, but they would never be okay with Chris Brown dating their little sister. No one would.”

Meanwhile, Chris' new relationship with the model is reportedly making his ex, Karrueche, jealous.

The source explained to RadarOnline.com: "Chris knows that Karrueche cannot stand Kendall and it really pissed her off when she saw her sitting on his lap. Why do you think Kendall is best friends with Justin Bieber and only hangs out with supermodels?

"She is a smart girl and everything she is doing right now is for her own selfish gains. She doesn’t realise that her reputation as being a starf****r is actually only going to hurt her in the long run."
