Kim Kardashian's holding out on Brody Jenner.

The stebsibs were out at M.I.6. in West Hollywood last night to celebrate Brody's 26th b-day, partying it up with fellow family members Khloé and Rob Kardashian along with L.A. Lakers star Lamar Odom (accompanying Khloé, if enquiring minds must know) and fellow reality star Brittny Gastineau. Special guest rapper Too Short performed for the crew.

Asked what kind of present she brought for Brody, Kim said she came unarmed. "Not here. Not at a club. I'll give it to him at home."

Brody, meanwhile, avoided all media and snuck away to his party bus after the club.

Noticeably MIA: Brody's gal-pal (and Joe Francis nemesis) Jayde Nicole. Earlier in the evening she tweeted: "So bummed and upset :( its my boys official big bday bash w/ all of our friends tonight and I am staying in all by myself... I wanna cry :("
