The 27-year-old spent Christmas in rehab after losing his place on the Essex reality show last year.
But on a recent night out with best mate Mark Wright, 28, and his 27-year-old fiancée Michelle Keegan, Arg looked better than ever.
Posing next to the beautiful couple, a svelte Arg captioned the snap: “Looking forward to @sheeshchigwell later tonight with the gang! #CheatMealNight #DreamCake x [sic]”
It seems like Arg has been spending a lot of time with Mark and his wife-to-be, as the week before he shared another picture of him tucking into some food and wrote: “Sunday dinner @sheeshchigwell was worth the wait all week! Great times with @MissJessWright_ @michkeegan @MarkWright_”
While the rest of the TOWIE gang jetted off to Tenerife this month to start filming for series 14, Arg’s future on the show still looks uncertain.
However his on/off girlfriend, and co-star, Lydia Bright, 25, confessed this week she hopes to see him return.
While appearing on This Morning Lydia praised Arg, saying: “He’s doing really well at the moment… and we’re all praying that he comes back sometime during the series.”
Elliott Wright, 34, added: “He’s doing amazing. He’s in the gym every day, he’s working hard, [looking at Lydia] he’s got his inspiration…
“He’s lost a lot of weight… he’s done fantastic, I’m really proud of him. He was in a bad place and he’s come through it really strong.”

From Essex glamour to understated chic: TOWIE makeovers
1 of 9Lauren Pope
Wow – is this even the same person? These days stylish Lauren is a far cry from her perma-tanned former self.
2 of 9Lucy Mecklenburgh
Gone is the big hair and the orange tan, and these days Lucy oozes sophistication.
3 of 9Lauren Goodger
Apart from the darker hair and plumper lips, Lauren hasn't changed much. Her love for selfies has defintiely grown considerably, though.
4 of 9Sam Faiers
What's the betting fashionable Sam wouldn't be caught dead in that 'Essex' necklace these days?
5 of 9Amy Childs
What a difference four years makes! Businesswoman Amy has toned her whole look down and looks fabulous for it!
6 of 9Jessica Wright
Mark's big sister's motto must have been 'less is more'. But these days she's sexy without flashing too much flesh.
7 of 9Billie Faiers
Yummy mummy Billie rarely puts a foot wrong nowadays and we much prefer her as a blonde.
8 of 9Lydia Bright
Ultra chic Lydia is arguably one of the trendiest TOWIE girls now, but it hasn't always been that way...
9 of 9Maria Fowler
Just like Popey, Maria is almost unrecognisable! The red hair is much more flattering on her skin tone.
