Jay Z just gave J. Cole the ultimate birthday gift. We're talking the kind of present that shits on everything one could possibly receive.

Not only did Hov make a surprise appearance at Jermaine's concert at Madison Square Garden, he also gave him his original Roc-A-Fella chain. Yes, the original.

Here's what Jay Z had to say about it during the show:

"It's your birthday but that on your neck is my original Roc chain, and it's yours."

Happy birthday, Cole.
