A picture surfaced this week appearing to show the Essex favourite, 26, taking a photo of himself while standing stark naked in front of a bathroom mirror.
But rather than get embarrassed about the leaked image, the crooner has laughed it off in a brief Twitter message posted 27 March.
Arg said: "#NakedSelfie is over 1 & 1/2 years old, To someone who I was in a relationship with & trusted! Least my tan looks good lol #CaughtSlipping."
There's no word yet on who exactly the picture had been intended for or how it got from their phone to the rest of the world, but perhaps Arg will spill more details in his brand new book?
Arg's autobiography Tales Tantrums and TOWIE: Living It Arg was released this week, which promises lots of info on his love life, weight struggles and what really happens behind the scenes in Essex.
He told Reveal: "It's about me growing up as a child. So losing my virginity to my ex girlfriend Lydia Bright and falling in love with her. Also, how I became best friends with Mark Wright and then years later joining The Only Way Is Essex. My life completely changed from being a normal Essex boy to starring on a BAFTA award-winning TV show and hanging around with celebrities.
"I was going from job to job and I didn't know what to do with my life. I came home from Spain having no money, no girlfriend and no prospects. Literally a month later I was on this humongous hit of a TV show. TOWIE was an absolute monster in the first few series and it still is now."
Arg added: "There are a couple of secrets in the book but there's so much more I could have told. I've toned it down a bit. It's a well known fact that I had a phase when I was cheating on Lydia, and obviously I really regret it now, but in the book it mentions a passionate kiss in the toilet with a former TOWIE cast member. I'm not going to say who it is."
