The latest JayBe sighting was in New York during Jay-Z's set from his "Heart Of The City Tour.'    Jay went to the DJ booth and vegan to cue up tracks like his classic joints from "Money Ain’t A Thang," and "Hard Knock Life," to "Bonnie & Clyde" and after the first few seconds Jay would say "F*** Dat!" and keep it moving.  Well he played "Crazy in Love" and again said "F*** DAT" but this time with a grin, as soon as he did that Beyonce hits the stage and walks over to Jigga and performs her "Uh Oh" bootylicious dance that had Jay-Z laughing and the crowd going crazy, it was defiantly a show-stopper!
