Dallas Mavericks owner Mark Cuban is turning into a mentor for The Situation. The other night, he was spotted giving Mike Sorrentino some advice over dinner at a Meatpacking District eatery where The Sitch and his business partners had their eyes “glued on Mark” and “were hanging on Mark’s every word,” a spy reports. The “Jersey Shore” star has landed himself a book deal, a workout DVD, a sponsorship with protein-infused Devotion Vodka, and a potential deal to become a part-owner of a gym in the Plaza Hotel. Cuban told us, “I wasn’t sure what to expect when he wanted to meet, but he is really into the business side of things. [Sorrentino] had a ton of questions about running his businesses, branding, and how to invest his money.” But he said they didn’t discuss working together: “He doesn’t need a job. He just needs to surround himself with smart people who make sure the deals he does do are good deals. And from what we talked about, it sounds like he has done that.”
