The 'Jersey Shore' star commemorated the occasion with a dapper Instagram pic.

Mike "The Situation" Sorrentino is celebrating a very special milestone.

The Jersey Shore star took to Instagram on Thursday to share a thoughtful and charming snapshot of himself -- looking dapper in a light grey tailored suit with patent leather dress shoes and a crisp black tie -- as he commemorated another year of life without alcohol.

"Celebrating 4 Years Clean & Sober?????," Sorrentino captioned the celebratory pic.

The excited post was met with a lot of love and support from his friends and fellow Jersey Shore: Family Vacation co-stars, including Nicole "Snooki" Polizzi, who commented, "So proud of you brother ❤️??."

The reality star also shared a smiling selfie of him and his wife, Lauren.

"We’ve got big news to celebrate!" Sorrentino captioned the pic, referring to his health and wellness milestone.

Speaking to Us Weekly, Sorrentino said, "I am grateful to be four years clean and sober, being my best self and living my best life."

The reality star admitted that the actual four-year anniversary isn't until Dec. 24, but that he plans on celebrating the accomplishment throughout the month.

"The comeback is truly greater than the setback," Sorrentino said. "I am showing my friends, family and fans by example that your current Situation is not your final destination and to never give up on yourself."

The celebratory posts come less than two months after the 37-year-old reality star was released from prison. Sorrentino served an 8-month sentence in the Federal Correctional Institution in Otisville, New York after pleading guilty to tax evasion.
