The 27-year-old recently underwent a dramatic transformation, something which he is keen to show off the results of in his best suit.
Speaking to Now! Magazine, Arg confirmed he will be taking girlfriend Lydia Bright with him to the showbiz wedding of the year.
He said: “We’re both really excited for it – it’ll be a very special day. I’ll be putting my best suit on and I’m sure Lydia will look lovely as she always does.”
TOWIE star Arg also revealed that bestie Mark, 28, and 27-year-old Michelle have been a big help in his lifestyle overhaul.
He continued: “Mark and Michelle have had me round their house for sleepovers and I’ve been training with Mark.
“It’s funny – in all the years we’ve been friends Mark would never invite me to go and play football with the lads.
“He’s so competitive, he always has to win. Now, he not only invites me along but he wants me on his team!”
Thankfully, after everything he’s been through, Arg is now the happiest he’s ever been.
“Everything I’ve ever wanted is actually happening and it’s quite scary that it’s all going so well. You’ve just got to really want it and work hard for it – hard work and dedication.”
