Although the whole world assumes that Chris Brown is currently taken, it seems like Kendall Jenner could care less, as she reportedly wants to date him anyway.

The supermodel was reportedly seen cozying up with the "Loyal" hitmaker while partying with younger sister Kylie and another R&B star, Trey Songz, in Los Angeles on the weekend of MTV Video Music Awards.

According to Us Weekly, the couple went back to Brown's place on Aug. 25. "They hung out with friends until 5 a.m.," a source close to Jenner revealed.

Being aware that the "New Flame" crooner is in a relationship with on-again girlfriend Karrueche Tran, the "Keeping Up with the Kardashians" star is apparently still holding out hope. "She's obsessed with Chris!" another source said, adding that Brown also "thinks [Jenner]'s really cute."

Meanwhile, Tran is worrying about the wrong woman -- her longtime love rival Rihanna. Urban Islandz reported that since Brown started speaking to his ex-girlfriend again, the Kill designer is in "panic mode" and afraid that he will dump her.

"Karrueche knows she can't walk in Rihanna's shoe when it comes to Chris," an insider said. "She is worried and for good reason because both Chris and RiRi love each other a lot and anything is possible between those two."

But for now, Chris Brown has promised Karrueche Tran that he will be with her. "Karrueche has been loyal to Chris through thick and thin, and he promised that he will remain by her side but only time will tell," the insider added.

In addition, Kylie Jenner has reportedly been hooking up with Tyga, who recently split from fiancée Blac Chyna. The pair was spotted at Universal Studios on Sept. 20. An eyewitness claimed that they arrived with a group but left on their own.

Then what is mom-manager Kris' opinion on the Jenner sisters' dating style? "She hates that they're into bad boys," a source said.
