The former TOWIE star told Reveal that although Arg is one of his closest friends, he's not sure about the couple rekindling their romance at any stage in the future…
Joey, who is promoting his new show, Educating Joey Essex: Reem Queen At 90, told us: "I don't think Lydia should take him back… why should she? He's a nuisance! He's my mate, but if a girl made that many mistakes with me, she'd get dumped – fast!"
Lydia and Arg split earlier this year, with Lydia saying she had "no choice" but to end things, amid allegations Arg's partying was out of control.
Arg is currently working on himself at various boot camps, while Lydia has just jetted to Las Vegas with girlfriends. She said recently: "I think I'm the happiest I've ever been in my life. I know that's a bold statement but I honestly do."
The couple initially met at the Duke of Essex Polo seven years ago, and both appeared in the first series of The Only Way Is Essex. Lydia left the show in 2012, saying she needed to get away from Arg in order to move on after they split, but she returned two years later.
Their romance picked up again and although there were issues - Lydia asked Arg to write a list of women he'd been unfaithful to her with and expressed concern at his drinking – they had seemed happy during the 17th series of the show, even flat hunting together in March.
Speaking on ITV's Lorraine earlier this month, Lydia confirmed: "Me and James actually broke up, which was a tough decision to make but I kind of felt I didn't really have a choice."
When Lorraine Kelly suggested that Lydia will always love Arg, the Essex star agreed: "Of course, yes I will." Lorraine then added, "I could shake him sometimes!" to which Lydia replied, "You and me both, Lorraine!"
