Mick – who was also the former owner of Essex nightspot Sugar Hut, which featured on the ITVBe reality series – was found dead at his home on Thursday.
Essex Police have confirmed they are not treating his death as suspicious.
A police statement read: “We were called to an address in Brentwood Road, Bulphan shortly before 3.15pm on Thursday 21 January.
“Sadly, a man inside was pronounced dead. His death is not being treated as suspicious and a file will be prepared for the coroner.”
Mick was introduced to TOWIE fans in the second series in 2011 as the father of established cast member Kirk Norcross.
He appeared in six series of the show until his departure in 2013.
During his time on TOWIE, Mick memorably caught the eye of Gemma Collins, who attempted to pursue a romantic relationship with him.
He also had romances with Chloe Sims and Maria Fowler on the show.
A number of Mick’s former co-stars have lead the tributes to Mick online.
James Argent wrote on his Instagram Story: “A true gentleman & a very kind man! RIP Mick.
“Many amazing memories, So Sad! My thoughts are with his family.”
Jessica Wright also posted on her Instagram Story, writing: “Terribly, terribly sad. Always such a gentleman and so kind. Devastated for him and his family.”
Mario Falcone tweeted he was “shocked and heartbroken” at the news.
