On last night's episode of the ITV2 show, viewers saw Lydia making breakfast in bed for Arg after he spent the night at her house.
"I never thought in a million years I'd be waking up next to you!" gushed Arg.
Later in the day, the loved up singer couldn't resist rounding up his guy friends to tell them all about what had happened between him and Lydia. (So much for not kissing and telling, then!)
"Me and Lydia made love and it was amazing and I want to tell the whole world!" Arg shouted, adding Lydia had been "completely sober" when it happened.
"I sort of mentioned to Lydia if I could come round. In front of everyone she said no, then as soon as I went home and she was by herself, she said, 'Are you going to come around?' It was last night - and tonight!"
He later said: "I never thought I'd get her back. The only thing I'm worried about is I'm dangerous in love at the minute. I'm so happy but also a bit overwhelmed by it all. This thing built up in my head for two years and I never thought I'd had a chance and it's happening."
But while Arg was clearly thrilled, it seems Lydia was being more cautious about what had happened.
Speaking to her mum Debbie during the episode, she got tearful as she admitted she was confused about what exactly she wanted right now and didn't want to lead Arg on.
"I don't want James to think I'm becoming his girlfriend. I'm not saying I don't want a relationship now, but it's made me think maybe there could be a future for us in the long term, but not now as I'm on the fence."
Debbie advised her daughter to think with her heart rather than her head, and pointed out plenty of other couples had gone back and forth in their relationships.
"You're not the first couple this has happened to and you won't be the last. Elizabeth Taylor and Richard Burton went through this seven times."
At the end of the episode, Lydia met with Arg while he was trying on suits for Leah Wright's wedding in Spain. He'd previously invited her to come as his date but she wanted to set some ground rules.
"I don't want your head to run away and plan a future with us together when mine isn't there," she said.
When Arg quizzed whether they'd be sleeping together in Spain, she was rather emphatic in saying: "No!"
Hmm. We wonder.
We'll have to tune in on Wednesday to find out what happens next!
After the episode aired, Arg tweeted: "Hope you all loved Tonight's #TOWIE She does make me so happy! @LydiaRoseBright sorry if im a prat at times! x."
