Actress and model Karrueche Tran recently appeared on Kylie Jenner’s cooking show, Cooking With Kylie, but instead of focusing on the dishes, she had other things in mind.

According to an insider, Tran, 27, warned Jenner, 18, to watch her sister Kendall and tell her to steer away from R&B star Chris Brown.

While filming the cooking show episode, Tran reportedly was constantly on Kylie’s ear, telling her to advise Kendall, 18, not to get too close to the hot-headed singer.

The source said that Tran described Brown as a “dog,” and was only affectionate and loving to her before he got what he wanted. After they became sexually intimate with one another, their relationship went downhill.

Meanwhile, Brown and Kendall were reportedly spotted hanging out together in Paris during Fashion Week. If rumors are true about the budding love affair, then Tran’s warning is definitely spot on.

It is easy to understand why Tran is frustrated with her ex-boyfriend. The two had a social media feud on Instagram on Friday, after the “Zero” singer questioned Tran’s talent.

Brown slammed his ex-girlfriend on the social media site and implied that his relationship with her is one of the reasons she gets movie roles, though her movies go straight to DVD.

He then wishes her to have “the most successful career ever.”

Tran responded by posting a link to “Back to Sleep,” which is a recent remixed track by Brown.

“You’re calling me a b—h yet you’re screaming my name in a song about getting back together?” she posted.

Tran then said that Brown should just move on with his life and focus on his lovely daughter.

Karrueche Tran and Chris Brown dated on and off for more than four years, before splitting in March 2015, after reports that the “Loyal” singer has a child with another woman.
