Sam Faiers "lost the plot" when Joey Essex began romancing Amy Willerton.
The former 'The Only Way Is Essex' star has confessed she refused to watch her ex-fiance flirt with his beauty queen co-star on 'I'm A Celebrity ... Get Me Out Of Here!' following one of their break ups in 2013.
She said: "When Joey was in the jungle, I lost the plot. I can't remember a time when I was so depressed. I refused to watch him. What I did was become obsessed with how things were going to pan out for us and with being the thinnest I could be for when he came out."
The 24-year-old beauty - who split from Joey for good in October last year - managed to win Joey back after being diagnosed with Crohn's disease following her stint in the 'Celebrity Big Brother' house shortly after Joey left the jungle, and Sam admits her extreme weight loss left her feeling self-conscious.
She explained: "I was nearly three stone lighter than before I went into the 'Celebrity Big Brother' house. What I saw in the mirror made me gasp in horror - my hip bones jutted out so far and were so sharp."
Sam also previously dated her former co-star Mark Wright but she's confessed that at the time she didn't think he was boyfriend material.
In an extract from her new book 'Secrets & Lies', she says: "The only person Mark thinks about for longer than ten seconds is Mark. He's a decent guy deep down, but he was a player and not someone I could trust. He wanted it all on his terms. Luckily he seems settled with Michelle Keegan - she's a good match and won't put up with any nonsense."
