Jemma Lucy was axed from 'Ex on the Beach' after grabbing her co-star's throat.
The 28-year-old star was removed from the contestants' house in Thailand after attacking Kayleigh Morris, 28, on the MTV show after a fall out over hunk Ashley Cain, who had bedded Jemma after dating Kayleigh.
An insider told Daily Star Online: "Kayleigh made a dig at Jemma that she dresses badly, so Jemma explained she was meant to be Hawley, but Kayleigh just carried on the insult.
"That was the icing on the cake for Jemma, she leapt up out her chair, was scratching at Kayleigh's face and at one moment grabbed her at the throat.
"Security had to come in and escort her out, before sending her to isolation for two days after which producers eventually told her she had been axed."
Before the incident, which will set to air on next week's show, Kayleigh attempted to wreak revenge on Jemma for bedding Ashley by throwing her clothes out of the window and her make-up into the pool.
The insider added: "It all started because Kayleigh was growing jealous of Jemma's relationship with her ex, Ashley.
"Jemma and Ashley were really getting on, and it wasn't just about sharing a bed, their relationship was becoming more than sex for them.
"Jemma did her best to ignore it as she clearly didn't want to give Kayleigh a reaction, but she snapped after downing alcohol.
"She just got really drunk one day as she had been waiting all afternoon at the beach for an ex."
Jemma previously enjoyed a fling with Geordie Shore's Gaz Beadle, who was in a relationship with Charlotte Crosby.
She has also been embroiled in an argument with Holly Rickwood when she tried it on with her ex David Hawley.
