In a new ITVBe video on YouTube, Arg reveals what he loves about Lydia the most.
He says: "There's many favourite things I love about Lydia. Personality-wise I love the fact that she makes me laugh a lot and we have a really good connection and banter together. She's a very loyal girlfriend and behind every successful relationship is a strong woman, which Lydia definitely is.
"As much as personality is the more important thing, looks-wise, I love her bottom. She reminds me of a young Kylie Minogue and I do fancy her. She's got a nice little squidgy bum!"
Childhood sweethearts Arg and Lydia rekindled their romance at the end of the last series. Throughout the show's history, viewers have seen the ups and downs of their relationship, but following a stint in rehab over Christmas, Arg finally won back his girl.
Now the pair are as loved up as ever, and they couldn't have looked happier on the recent cast trip in Marbella as they sunbathed poolside and went out on romantic dates.
Speaking on ITV's This Morning last week, Arg said: "At the moment, me and Lydia are in an extremely good place. We got together two years before TOWIE existed. We've been together since we were teenagers.
"We've had our ups and downs, as many people have seen, but at the moment we're stronger than ever. I've moved in with Lydia now and we're very much so loved up."
