Whoa. This is one picture we did not expect to see!

Kendall and Kylie Jenner were photographed in some pretty tight embraces with Chris Brown and Trey Songz recently, as evidenced in several seriously cozy pics the 'Trigga' rapper posted on Instagram over the weekend.

According to Us Weekly, Kendall, 18, and Kylie, 16, were at a house party with Brown, 25, and Songz, 29, over the weekend, and the foursome looked a little too close for (Kris and Bruce Jenner's) comfort, with Kendall being hugged by Trey Songz from behind as she pouts seductively into the camera. While her young sister Kylie was not as wrapped up in Brown's arms, he did still have his arm around her as he cocked his head to the side and sported some kind of cigarette hanging from his mouth. (Just a warning -- one of the pics is a little NSFW!) Definitely a little provocative -- though, of course, the Kardashian-Jenner clan aren't exactly strangers to the rap scene, considering Kim is married to Kanye West and Khloe is dating French Montana.

In other eyebrow-raising Chris Brown news, his new neighbor recently spoke out to TMZ about living close to the singer -- and let's just say, he did not hold back.

"It can be the devil. I can care less. I don't care if they're having orgies. It can be Saddam Hussein for all I care, as long as he doesn't trespass on my property," the neighbor reportedly said. "If he does, I'll shoot him." Wow. Harsh reaction much?
