Love & Hip Hop — Kardashian style! Following in the stilettos of big sisters Kim and Khloe Kardashian, Kendall and Kylie Jenner are hanging out with hip-hop stars, multiple insiders reveal to Us Weekly.

Kendall, 18, partied with Chris Brown the weekend of MTV's Video Music Awards. The supermodel, who just finished walking in New York and Paris Fashion Week shows, went back to Brown's place on Aug. 25. "They hung out with friends until 5 a.m.," a source close to Kendall tells Us.

Brown, 25, however is back on with his girlfriend Karrueche Tran. (The tumultuous couple were on a break the weekend of the VMAs.) Still, a second source tells Us that Kendall is still holding out hope. "She's obsessed with Chris!" the insider says. The "Forever” hit maker — whose most famous ex, of course, remains Rihanna — "thinks she's really cute."

As for Kris and Bruce Jenner's youngest daughter? Kylie, 17, has been hooking up with Tyga, another pal tells Us. The "Rack City" rapper, 24, (whose real name is Michael Ray Nguyen-Stevenson) recently split from his fiancee Blac Chyna. The exes share a 23-month-old son named King.

Kylie and Tyga were spotted at Universal Studios on Sept. 20, checking out the park's Hollywood Horror mazes. An onlooker tells Us that the two arrived with a group, but took off on their own as they explored the mazes.

What's also interesting about their relationship is that Tyga's ex Blac Chyna is close friends with Kylie's big sis Kim; The two even attended Kardashian's May wedding to Kanye West in Florence together. "Tyga is friends with Kanye, too," the source says.

Momager Kris Jenner, though, is not pleased with her youngest daughters' dating lives. "She hates that they're into bad boys," an insider tells Us.
