Arg, who has never hidden his love for food in the past, disappeared earlier today (9 August) while filming new TV show Celebrity Super Spa.
His co-star, former Coronation Street actress Helen Flanagan, spent ages hunting him down before finally catching him redhanded with a mouth full of fries.
To make sure fans knew exactly what he'd been up to, Helen then took a picture of Arg and shared it with her 360,000 Twitter followers!
Alongside the photo, Helen commented: "Couldn't find @RealJamesArgent anywhere for about half an hour and here is, in the boss' chair eating McDonalds." Naughty boy!
