Jay Z pulled out all the stops Tuesday night during J. Cole "s
b-day concert in NYC -- surprising the 29-year-old rapper with an incredible
guest performance ... before handing over a priceless piece of rap history.
The crowd went WILD at the Garden -- Hov came on stage and performed
"PSA" while J.Cole stood in shock ... it was awesome.
But the best moment by far was when the music stopped ... Jay
Z pointed at the diamond chain around J. Cole "s neck -- Jay Z "s original Roc-A-Fella
chain from when he founded the label in the 90s.
J. Cole thought he was wearing the chain on loan for the night
... but Jay Z turned to him and said, "That, on your neck, is my original
Roc chain -- and it "s yours."
Legendary.
