Mike ‘The Situation’ Sorrentino dons ‘Jersey Shore’-inspired Halloween costume

Halloween is always a Situation.

Every October, Mike “The Situation” Sorrentino gets an influx of photos of “Jersey Shore” fans dressed up as him — complete with a neck brace and sunglasses — so this year he decided to entertain them — by going as himself.

The now-infamous scene that inspired the costumes — of the reality star ramming his head into a concrete wall on the MTV series — aired over 13 years ago.

“As we get closer to Halloween, I start to get inundated,” he told The Post.

“I love my fans and I repost everybody … You’ll look at my Story and you will see all the neck braces and the sunglasses.”

Sorrentino, 42, who has 3.4 million followers on Instagram, said he is always touched by those who dress up as him each year. So he wanted to honor them with his costume choice this time around.

“I wanted to surprise the fans and bring the look back with a slight twist,” said Sorrentino, who added a hospital gown to the ensemble.

The shocking reality TV moment — which landed him in the hospital with a sprained neck and concussion — is from Season 4 of the show, when he was going through opiate withdrawal.

When his co-star Ronnie Ortiz-Magro picked a fight with him, he went into a rage, and ran head-first into the wall of the house they were staying at in Florence, Italy.

“It is hard to watch because I was going through a lot of pain at the time. We’re watching one of the biggest reality TV shows in the country … We were getting six, seven, eight million viewers per night, which was unheard of and a record for MTV,” said Sorrentino, who now stars in the show’s spinoff, “Jersey Shore: Family Vacation,” now in its seventh season.

“And I ran into a concrete wall made by Caesar, sprained neck and concussion while I was going through withdrawal. I mean, man, you just can’t make that up. You just can’t script that.”

Now, Sorrentino, who will be celebrating his ninth year of sobriety on Christmas Eve, is gearing up to open his own treatment centers next year — an idea he manifested after serving eight months in federal prison for tax evasion.

“When I actually got out of prison, I had a meeting with my publicist and my manager and they said … ‘We want to get your five to seven year vision board,’” recalled Sorrentino, who just signed the lease for the first of his Archangel Centers in Mercer County, NJ.

“And the first thing on my wish list was to open up my own treatment centers.”

The reality star, who himself went through four stints of rehab, told The Post last year that he was addicted to the painkiller Roxicet, equivalent to a 30 milligram Percocet, and at his worst, was popping 10 of them three times a day.

Sorrentino named the facilities after St. Michael the Archangel, and said although his centers aren’t religion-based, his Catholic faith helped him through addiction.

“They say that most addicts believe in God because they’ve met the devil, and that statement really stuck with me,” he said. “I believe that God spared my life so that I can tell my story to help other people.”

The dad of three, who will be running the centers with his wife, Lauren Pesce, will be taking a hands-on approach with clients, “doing small groups, Q&A’s, tours.”

“When I show up for speaking engagements … I usually don’t even have to say a word and people are cheering and screaming and they love me and my story. And I’m like, ‘You know what? I’m going to use that for good,’” he said.

Pesce, who lost her brother Christopher to an overdose in 2013 when he was 25, will be an integral part of the process.

“Well, that’s the boss right there,” Sorrentino said of Pesce, his college sweetheart, whom he wed in 2018.

“She’s going to be coming from the family aspect of it … we’re going to dedicate a scholarship to honor her brother’s memory.”

Before his foray into television, Sorrentino, who grew up in Manalapan, NJ, was the local drug dealer — and said his childhood pals, some of whom recently attended his daughter Luna’s baptism, are amazed at his transformation.

“One of my friends said, ‘I’ve seen the good, the bad, the ugly and now the beautiful,’” he recalled.

This December, “Jersey Shore” will celebrate its 15th anniversary, and Sorrentino, who lives in Holmdel, NJ, is ready to celebrate the milestone.

“I’m thinking I may have to try to organize a big party … because me and the cast are so close,” he said.

He is also not ruling out the idea of a spinoff show centered around his family.

“I wouldn’t say no to that … something about the Situations,” he said.

“We have a beautiful family, and we got a lot going on. You never know what the future will hold … It could be Governor Situation in a few years.”
