Cam Newton still had so much energy left after beating up on the AZ Cardinals Sunday night -- the Panthers QB hit a North Carolina nightclub to celebrate ... and even did some dabbin' in the DJ booth.
Newton went to Label nightclub in Charlotte -- where he partied with DJ Holiday and rap superstar Juvenile (who even performed, "Back That Ass Up!!").
By the way, bar staffers tell us Panthers defensive end Charles Johnson bought shots for EVERYONE IN THE CLUB.
In fact, the DJ made an announcement during the party --"Charles Johnson wants to buy everyone shots! So go to the bar."
We're told in the end, Johnson paid for hundreds of shots!!!!
Waiting for your permission to load the Instagram Media.
All in all, helluva night to be a Panthers fan.
