Rob Kardashian -- Family Shows Up for Birthday ... Where's Khloe?

The Kardashian family is once again a united front, celebrating Rob's 29th birthday in Malibu, with one notable absence.

Kris, Kim, Kylie, Kourtney, Kanye, North, Scott, Penelope, Mason, Corey and Tyga all chowed down at Nobu Saturday night for an early dinner.

Khloe was missing. On the surface it's interesting because she kicked Rob out of her house after finding him in her kitchen with Blac Chyna, but the hatchet seems to be buried. Khloe says she's sick so we're guessing that's why she was a no show.

Interesting ... Blac Chyna was nowhere in sight ... real progress takes time.

The crew disbanded at around 8pm.
