50 Cent got into some funny business while shooting the humorous commercial for his Street King energy drink with comedienne Joan Rivers. The unlikely duo worked up a sweat and shared laughs at Planet Fitness in Harlem on Tuesday.

“I tried to put together the odd team, not the A-team,” the G-Unit mogul told “Access Hollywood.” “It has a lot of different layers to it for something that has to happen in 30 seconds.”

The 78-year-old star hit the gym wearing “athletic-inspired diva wear” including a $75,000 chinchilla coat.

“The premise of the commercial is I have no energy, I drink the drink, and I’m ready for fun,” explained Rivers, who gave herself the nickname 34 Cent.
