Sandra Bullock And You Are?

Sandra Bullock will probably win an Oscar this year but when she came face to face with another epic Oscar winner she got a quick Hollywood reality check.

Sandra was rushing into Craigs in Hollywood last night when she stopped dead in her tracks after spotting Sidney Poitier talking to some friends outside.

A humble Sandy approached Sidney ... in fact, she waited for him to finish a conversation and then introduced herself like she was some random chick.

The 86-year old actor kinda knew he recognized her ... but didn't necessarily know from where. However things quickly got all nice and kissy-kissy.

Their whole exchange is awesome ... you gotta see it!
