The Essex lads have been friends for years, and even though Mark is now engaged to Coronation Street star Michelle, they will still be seeing each other at Christmas.
Speaking about his festive plans, Arg tells Reveal: "I'll be staying at home in Essex this Christmas.
"I always go round to Mark Wright's house on Christmas day and this year won't be any different.
"I'm not entirely sure what he and Michelle have got planned, but I will definitely be seeing him. I haven't lost Mark to Michelle!"
Tonight, TOWIE's fans will be treated to the Christmas special episode of the reality show, The Only Way Is Essexmas.
In the show, Arg and his fellow co-stars travel to the east coast of England for a festive mini-break.
Arg says: "We all went and stayed in a log cabin in Norfolk and it was so much fun!"
Although Arg is staying in Essex for Christmas, he is travelling up north for New Year.
"I'm going to Rio Ferdinand's restaurant Rosso Manchester for New Year," he adds. "I've been there before and am really looking forward to it. It should be good!"
Arg is currently promoting Pizza Hut's new look Crawley restaurant, which marks the start of a £60 million investment in the chain.
