Oh look Kylie and Kendall Jenner are making new friends!

Apparently the reality star sisters can now count bad boy Chris Brown as one of their buds. The 18-year-old and 16-year-old were chillin' and illin' with the 25-year-old rapper at a wild house party over the weekend.

Umm we wonder if Mama Bear Jenner knows just who were youngest ones are consorting with? (Of course she does, those girls don't breathe without their mother's say so -- Kris Jenner was probably the one taking the pictures and uploading them on Instagram.)

In the pics, the girls seem cozied up with Chris, who was recently released from jail, as he showed off his grillz. The house party looks like some it was a boisterous affair -- Chris certainly seemed like he was enjoying flicking off the camera.

The Jenner girls also partied down with rapper Trey Songz, who looked like he was manhandling Kendall. We aren't sure if Kris is going to love these pics!

We aren't positive how Chris befriended the gals -- but we are sure Justin Bieber had something to do with it.

While Kendall and Kylie might be Chris Brown's new BFF, not everyone is a fan of Breezy. Apparently Chris' new Agoura Hills neighbor is having none of the notorious party boy's wicked ways, even threatening to shoot him if necessary.

The unnamed neighbor says he doesn't care what the "Turn Up the Music" singer does on his own property -- but that if he steps onto his property -- Chris will have hell to pay.

"I don't care if they're having orgies. It can even be Saddam Hussein for all I care, as long as he doesn't trespass onto my property. If he does, I shoot him," said the disgruntled homeowner.

Let's hope Chris stays on his own 8,000 square-foot property -- otherwise those dancing feet will be dodging bullets!
