Jess joined Arg on the This Morning sofa today to talk about his stint in rehab over Christmas, and his return to TOWIE after being suspended for excessive partying.
Reality star Arg said entering rehab was the "best decision" he has ever made. He explained the downfall of his relationship with Lydia sparked his decision to seek treatment.
Jess said seeing Arg struggle was tough. She explained: "It was horrible because I felt like he wasn't being himself. He wasn't reacting to anything in the way that he used to. You couldn't really get any sense out of him, he was just not Arg.
"I can't believe that he made the decision to go and did it and got through it over Christmas. He did it, and came out and kept to it. I think that's so admirable and I think it could be the making of him again if you like."
Turning to Arg, who showed off his fitter and healthier look, Jess declared: "I'm just so proud of him, he looks so handsome!"
Meanwhile, Arg also thanked Jess for her support, saying: "Jess is like a sister to me. I've had sleepovers round hers, so she's let me stay on the sofa!"
