Since appearing on that show, Sorrentino has been a guest on TV series including The Howard Stern Show, The Tonight Show with Conan O'Brien, The Jay Leno Show, Lopez Tonight, SportsNation, Chelsea Lately, The Ellen DeGeneres Show, and Conan.
Sorrentino made more than $5 million in 2010, the second highest of any other reality star after Kim Kardashian. This money was accrued through endorsements with Devotion Vodka, Reebok Zigtech shoes, as well as a ghost-written autobiography, a rap song, a workout DVD, a vitamin line for GNC, a clothing line, and appearances on Jersey Shore and Dancing with the Stars.
In March 2011 Sorrentino appeared on the Comedy Central Roast of Donald Trump. His performance became a point of mocking that the other roasters, like Jeff Ross, capitalized on. In August of that year, Sorrentino was offered a "substantial" sum of money by fashion retailer Abercrombie & Fitch not to wear the company's clothes. A spokesman for the company explained that "Mr Sorrentino's association with our brand could cause significant damage to our image." In November 2011, Sorrentino filed a lawsuit against A&F after they made shirts that read "The Fitchuation" and "GTL...You Know The Deal."
On March 21, 2012, Sorrentino confirmed that he had checked himself into rehab "to get control of a prescription medication problem" he had with oxycodone. He checked out of the Cirque Lodge treatment center in Utah on April 4, 2012.
In September 2014, Sorrentino was charged with tax fraud, allegedly avoiding paying taxes on $8.9 million. According to the US Attorney, Sorrentino and his brother, Marc, established S corporations that paid for personal expenses and failed to report income. In April 2017, further charges were levied against Sorrentino and his brother, alleging tax evasion and the structuring of bank deposits to avoid reporting thresholds.
In 2015, he was a participant on the fifth season of Marriage Boot Camp: Reality Stars with his partner, Lauren Pesce.
In 2016 he was a participant on the 9th season of Worst Cooks in America.
In April 2017, Sorrentino appeared on We TV's Marriage Boot Camp: Reality Stars Family Edition with his brothers Marc and Frank Sorrentino.
