At his Mad Hatter-themed party this week, the reality star gave Lydia the intimate list… perhaps as a way to make a fresh start and rekindle their romance?
Viewers of the ITVBe show know Lydia and Arg have a long history together… a history that perhaps isn't actually quite in the past.
On the last episode of TOWIE, we learned Lydia had split from boyfriend Ben because she just didn't feel the same spark with him that she'd felt with Arg.
She also admitted she had a soft spot for Arg still.
"I do still have that soft spot for him but whether we're meant to be together or not, I'm confused," she admitted. "I've been hanging out with James and he makes me laugh, and then it makes me realise how Ben doesn't make me laugh."
After learning the news, Arg said: "Me and Lydia have always been flirty, but with or without being together, we're just having fun, it's nice. The fact that she's single makes it a bit easier if anything potentially was going to happen down the line, as friends or more, so who knows?"
Lydia, meanwhile, said: "You can never say never to anything but at the moment I've only just broke up with my boyfriend. But never say never, me and James get on really well, but who knows?"
TOWIE concludes its current series Sunday night at 10pm on ITVBe.
