On last night's show (3 November), viewers saw Mario and his dog Bentley meet up with Lucy over coffee to discuss their relationship.
The couple split in April following Mario's admission to cheating on her during their relationship. But during their chat, it appeared that romance could be back on the cards for the former lovers, after Mario confessed his true feelings for her.
However, straight after the show, Mario set the record straight, tweeting: "There will be no reconciliation guys... Mutually decided that we should be civil and that's it.... I wish her all the best in the future!"
During Sunday's episode, Mario told Lucy that he was still in love with her. He said: "I go on dates and the girls are very beautiful and they're really nice and stuff, but they're not a patch on you, it's weird. You've set such a high benchmark. It's true, I'm only telling you.
"I know that you said to Debbie that you are worried you won't find someone that loves you as much as I did, which I know is probably not far from wrong."
Lucy explained that she didn't want it to be awkward between them anymore, but also remained tight-lipped about her new romance with Tom Pearce.
Earlier in the day, Mario also spoke to Jessica Wright about Lucy, saying he had learnt from his mistakes.

He told Jess: "Before Vegas I told her I wanted to be with her. I still love her and I will always love her but she chose Tom."
Later on in the show, Lucy and Tom also had a chat about their romance at James 'Arg' Argent's bonfire party.
Tom told Lucy: "It's pretty obvious that you don't really know what you want at the moment. The best thing for me to do, to simplify that for you is to remove myself from the equation and let you be on your own.
"The hardest thing about the whole situation, is that I feel like I can make you happy."
A confused Lucy replied: "I don't know what to say. It's hard Tom because you know how much I like you as well."
TOWIE continues on Wednesday 6 November on ITV2 at 10pm.
