Lucy tweeted to her followers: “I finished with Mario 7 days ago. It took him a while to move on ... This has reassured me I made the right decision.”
She then posted the evidence of flirty messages between her former fiancé and a girl he'd previously met in his Twitter inbox.
In the messages, which reveal Mario’s phone number, Mario asks the girl if she still has his contact details, but was knocked back when the girl replied that she had actually deleted it “a while back.”
But then she revealed she erased the former TOWIE star’s number “to avoid temptation.”
The newly single Mario didn’t hide his excitement when sending her his mobile number and wrote: “Now you can let me take you out!! Woooo yay!!! Ha.”
But the girl’s response didn’t echo the Essex tailor’s excitement: “We'll see. Ha,” she replied.
Jess Wright sent her TOWIE co-star a sympathy message after seeing Lucy’s Twitter bombshell: “Just seen your tweet will message you hope you're ok x x love u,” tweeted Jess.
The on-off couple’s latest split comes after they reunited on TV a few weeks ago following allegations that Mario had cheated with Sugar Hut honey and new character on the show, Amy Broadbent.
Although Lucy hit back at Amy’s claims, it seems she has finally had enough of Mario’s behaviour and has finally ended the relationship.
From the looks of it Lucy, you've made the right decision!
