The original castmember has returned to work on the ITVBe series after a period of being banned from the show last year over his excessive partying.
Since then, he's successfully completed a stint in rehab and cleaned up his act.
Yesterday, producers confirmed Arg had been given the all-clear to resume filming and it's thought his first scenes could air as soon as this evening's episode.
These pictures show Arg embracing co-star James 'Diags' Bennewith on his return and getting fitted for a sharp new suit.
New year, new start, new look, new clothes!
As well as cleaning up his behaviour, Arg has been working hard on his health and well-being. He's lost weight and looks better than ever thanks to his new healthy lifestyle.
He told fans last night: "Very proud to confirm I've returned to @OnlyWayIsEssex. Thanks so much for all your love & support! Ready to create many more great memories! X."
TOWIE kicked off its 14th series on Sunday night with the usual mix of drama, romance and glamour.
Tensions ran high between Danielle Armstrong and Ferne McCann, while ex-couple Chloe Sims and Elliott Wright rowed at a nightclub after Elliott's family became involved in their breakup.
We also met new castmember Dan Edgar.
TOWIE continues tonight at a later time of 10.20pm on ITVBe, because of the BRIT Awards airing beforehand.
