While Lucy was over in the sunshine celebrating a friend's hen do, her ex was appearing on the latest episode of TOWIE, where viewers saw him chatting with his mum about Lucy.
Mario said: "I started talking to Lucy again. It seems to be a pattern of every two or three months… Then I get sucked back in, she'll drop me, I get upset."
He confessed he then usually started messaging girls to make himself feel better, prompting Mario's mum to reply: "It's not healthy, this Lucy thing. She reels you in then does what she does every time."
But if Lucy was feeling slightly stung by the comments, she wasn't showing it, instead posting pictures to Instagram showing herself looking beautiful and very glamorous in Sin City.
Wearing a neon yellow strapless dress to highlight her tan, there's no doubt the former reality star will have turned plenty of heads! She even posted a video of herself dancing in a packed nightclub, looking like she was having the time of her life.
Of course, as she's on her hols, there's always the high possibility she hasn't actually watched the latest episode of TOWIE yet, although Sam Faiers tweeted this morning she'd received a "drunken" FaceTime message from Lucy last night.
We wonder if Sam filled her friend in on all the goss?!
It's been all very dramatic on TOWIE recently following the surprise revelation that Mario has been in a secret romance with co-star Chloe Sims, who happens to be the sister of his best friend Charlie Sims.
They kept it a secret from everyone while they worked out hat was happening, but the secret came out earlier this month when they were pictured kissing in London.
Last night, however, viewers saw the duo call time on their fleeting relationship after Mario said he feared losing Chloe and Charlie as friends if something went wrong.
