Kendall and Kylie Jenner party with Chris Brown, Trey Songz

Looks like a good time was had by all, judging from the hugs, half-smiles and pouty kiss face.

Keeping Up with the Kardashians stars Kendall, 18, and Kylie Jenner, 16, were snapped partying with Rihanna's ex-boyfriend, Chris Brown, and Trey Songz.

Kylie shared one, too.

Dating rappers runs in the family.

Kim Kardashian, of course, is married to Kanye West. And Khloe Kardashian is dating French Montana.

Lord Disick, you need to start rapping!
