Despite having recently reunited with his childhood sweetheart Lydia Bright, Arg and Lydia kept their romance away from the flashing lights as they arrived separately at the Jog On To Cancer event on Thursday evening (9 April).
Inside the bash, Arg posed with his BFF Mark - MARG reunited!
Sharing a photo on Twitter, Arg said he was "having a great time" at the event "with the one and only @MarkWright_".
Arg returned to the 14th series of TOWIE after being suspended from the ITVBe reality show in October last year. Arg entered rehab over the festive season on a 28-day programme.
He explained on ITV's This Morning last week: "It almost seemed like everything I'd cared about just didn't seem to matter anymore. I wasn't turning up to filming sometimes, somtimes giving excuses, or I'd turn up late.
"I was letting my friends down like Jess and Mark Wright and I realised that if I don't go in there now, then I'd probably end up losing absolutely everything."
TOWIE's series finale wrapped up last Sunday, and by Wednesday, Arg was missing the show not being on screen.
He tweeted: "Last night just wasn't the same without #TOWIE haha I'm such a fan! #Geek #Loser."
Roll on Marbs!
