What does this mean then? On Tuesday evening Mario retweeted a Results With Lucy post promoting the fitness brand's live stream, and in doing so proved he was still a big supporter of his former flame.
One delighted follower noticed Mario's subtle social media action and praised the reality star for his show of support. They wrote: "Such a great guy for supporting Lucy! I hope you two get back together!"
This comes after Mario's Essex pal TOWIE star Pete Wicks hinted that a reconciliation was on the cards, telling one newspaper: "They aren't back together but they are definitely friendly again. I would say watch this space."
And that's not all - last month Mario uploaded (and then deleted) an cryptic post on Instagram alongside a heart emoji caption that read: "People who are meant to be in each other's lives will always find their way back to each other. They may take detours in life, but they're never lost." This came shortly after news of Lucy's split with Olympic medallist Louis surfaced.
Their break up after one year together came as a surprise to fans, as the pair seemed pretty loved-up. According to reports, Lucy and Louis split over differing views on settling down, but Louis has since dismissed such claims and told fans the truth was "very different".
So is Mario trying to win back Lucy? Last year he told Reveal that splitting from her was his "biggest regret."
He told us: "She was my big love. My friends still say they see us getting back together. What happened with Lucy is my biggest regret. That was a big life lesson. When you have someone you truly love, don't f*** up."
He and Lucy, who had got engaged during their time together (during a romantic TOWIE episode no less), split three years ago. Since then, she and Mario had moved on, with Lucy going on to date Louis and Mario embarking on an on/off relationship with ex Emma McVey. He was also linked to GB athlete Louise Hazel.
Hoping for a Mario and Lucy reunion? It would be seriously cute.
