Check out this video of UFC light heavyweight Jon "Bones" Jones hanging out with WWE superstar Brock Lesnar backstage following the latter's performance at Smackdown.
Jones said it was his first time to see Lesnar, who was a former UFC champion himself, perform live at the WWE.
Lesnar was forced to leave the UFC after suffering diverticulitis. His last MMA bout was when he lost via technical knockout to Alistair Overeem in 2011.
Jones, meanwhile, is currently taking it easy after suffering an injury while preparing for his title defense against Daniel Cormier.
He was supposed to fight Cormier in September, but due to his torn meniscus, the bout was moved to January next year.
