The Jersey Shore star worked with 50 Cent when he became one of the faces of the rap mogul's SK energy drink brand - a collaboration which has seen the pair develop an unexpected friendship.
"When me and 50 met, it was like instant chemistry," Pauly D explained to MTV News.
"Like, he gets me, I get him. You know what? We just have a bond. His business work ethic is just like mine. He's a hustler his whole life, and so am I, and we just clicked."
He went on to say that teaming up with 50 Cent for the SK brand seemed like the natural choice given that portions of the drink's proceeds go to charity.
"In other words, everyone who buys a shot feeds a starving child. And that's amazing to me. That kind of hit home, like this is something that I want to do, and then being in the business that I'm in, I need energy. So this is a great energy shot too," he said.
"One shot equals one meal. If you could do that, I'll buy shots all day long."
50 Cent recently released 'New Day', his new single featuring Alicia Keys and Dr Dre.
