(TMZ) -- Seems Kendall Jenner is already close enough with Blake Griffin to join in on steak night with his boys. 

The L.A. Clippers star and three of his guy friends hit up the Ocean Prime steak and seafood house in Bev Hills on Wednesday night ... with Kendall rounding out the group. 

Blake and Kendall have been hanging out for a couple of months now ... so no reason not to invite her along, right? 

So, when does Blake get his invite to girl's night?
