NORMALLY peppy Cameron Diaz was looking a bit bleary-eyed on the “Today” show yesterday at 7 a.m. promoting her new PG-rated film “Shrek the Third.” Before telling Meredith Vieira that “it’s like high school and celebrities are the popular kids,” the head cheerleader was at the Box on Christie Street for a live R-rated sex show - and stayed until 4 a.m. One spy told Page Six the show was “two topless girls rubbing slime on each other and wrestling, followed by a simulated ’sex show’ conducted behind a silk screen. Cameron was staring the whole time.”

Hey Cameron, wanna be my new best friend? (Oops, did I say that out loud?)
