However, while Lucy seems to have taken Amy Broadbent's claim that she slept with Mario as gospel, the 25-year-old reality star is maintaining that he remained faithful to his 21-year-old girlfriend.
Sitting at his mum's kitchen table, Mario is seen struggling to control his emotions as he said: 'This is going to be the worst day of my life.
'Lucy's my whole life. I haven't done anything, it just keeps happening every single time she always believes someone over me. I can't do this anymore.'
