Kendall Jenner's going public with her elicit relationship with Clippers star Blake Griffin -- spending Friday afternoon at one of the most public places possible, where there is guaranteed to be paparazzi and tongue-waggers -- Nobu, Malibu!

The young model and her NBA boyfriend wore skimpy clothing as temperatures reached 100, to the beachside, celebrity hotspot for a late lunch. Kendall rode with the baller in his matte black Rolls Royce and made a feeble attempt to hide her face as she entered the restaurant in a tiny black sports bra and jean shorts. But hey, KJ, we'd recognize those long legs and skinny hips anywhere!

Kendall has supposedly cooled with A$AP Rocky, though a source tells People mag the two are still seeing each other occasionally. Meanwhile, Griffin appears to have separated from his long-time, live-in girlfriend Brynn Cameron with whom he has two children. Hmmm ... seems the 28-year-old professional athlete is having more fun dating a 21-year-old supermodel than he was playing family man with a full house!
