So when TooFab asked his equally shredded co-star, Vinny Guadagnino, if he thought Mike would be able to keep up his post-prison bod, the "Keto Guido" let us in on a little secret.
"That's a good question," he said. "You know, you're actually gonna see that exact thing play out on 'Jersey Shore' -- how he reacts to it. Because we're going through that right now 'cause he just got out."
After serving an eight-month sentence for tax evasion, Mike was released from the New York facility. Naturally, it was a "Jerzday" -- as if his co-stars needed any more reason to celebrate. Before he did his time, though, "The Situation" had become known as "Big Daddy Sitch." He was happily "living his best life" and eating. A lot. Rare was the episode of "Jersey Shore: Family Vacation" he didn't mention "Funfettis."
But Vinny feels that was a bit of a pre-prison persona and believes Mike will remain the same "Situation" we met in 2009 -- at least physically.
"Mike actually by nature isn't a guy that walks around that eats Funfetti cake all day," he said. "I just think that at that part of his life, he was doing that because, you know, he did deal with addiction and recovery. And when we were filming the show, we would be going out to clubs, and Mike's vice was eating at the time. He loves his food. It gave him some joy and pleasure, and he knew he was about to go partake in this terrible prison sentence, so he was kind of just 'living his best life' before he went to do that."
"But by default, Mike's an active guy. He likes working out. He likes eating right," Vin added. "So I 100 percent believe that he's gonna keep it up, especially now that he has all these other wonderful things going on in his life, and he doesn't have that impending jail sentence coming up."
"Jersey Shore: Family Vacation," the reboot of MTV's original series, brought back all the faces we fell in love with almost a full decade ago. Yes, even "dirty little hamster" Angelina Pivarnick, who left the first go-around a few episodes into Season 1, returned. But lots had changed: Snooki and JWoww were married moms, Ronnie was about to become a father (and not with Sammi Sweeetheart), Vinny was half his original size and Mike was sober.
Even the way the show was produced had changed.
"We don't even know what we're filming nowadays," Vinny told us. "We just kind of film all year round 'cause it's about our personal lives now. In the past, we would go film a season in Miami, and that would be a season. Now, we film as our lives unfold, and MTV kind of splits it up into different kinds of seasons."
But Vinny doesn't necessarily mind having cameras in his face 24/7. In fact, he thinks it's better than the alternative.
"I do still like to party and stuff, but we are more than that," he explained. "Because we film it this filming style now, you're able to capture the real-life events that go on in people's lives, like Mike's prison sentencing, him going to court, him getting out. And now, the episodes that're airing are some of the most fun episodes that I've seen in a while."
"Not to be biased, but everyone is out in Vegas watching me strip at Chippendales," he bragged -- humbly, of course. "If we were in a house, that might not happen. So we do still get together and go on trips, but you're also able to see all these other different sides of us that're really fun or serious."
We'll finally get to see Vinny take the stage on Thursday's episode of "Jersey Shore: Family Vacation." And even though he looks like a pro in the preview, he told us he had his reservations about accepting the raunchy residency.
"When I first saw the offer, I kind of laughed at it because, like a lot of other people, I thought Chippendales was just like a male strip club," he said. "Even though I'm not a saint, because I've been on 'Jersey Shore,' I still don't wanna do something that's completely out of element of my brand."
But after doing some research, Vinny discovered he'd be among the likes of Tyson Beckford, Ian Ziering and Joey Fatone. "If they did it, maybe it's not so bad," he thought to himself. Once he went to go see a show for himself, he was sold. And the rest, as they say, is history.
"Jersey Shore: Family Vacation" airs Thursdays at 8 p.m. on MTV.
