Make Me a Supermodel Extra presenter Jasmine Lennard has been sacked for insulting panel judge Rachel Hunter.
Rachel Hunter had already been insulted by Lennard in the first series
Lennard, 21, dubbed Hunter "Rachel munter" on the Extra programme on Five's sister channel Five Life.
Production company Tiger Aspect said it had axed Lennard for her comments about Hunter, "our main panel judge and established face of the show".
Lennard was a contestant in the first Five series which sees wannabe models compete for a top modelling contract.
She angered Ms Hunter - a former model and the ex-wife of Rod Stewart - in the first series of Make Me a Supermodel by describing the 37-year-old as "spotty, finished and fat".
"I suggest she throws out the truckload of make-up she uses and hires a personal trainer," she added.
Tiger Aspect said it had warned Ms Lennard to watch what she said in her new role on the Extra show.
"It was very clear in her contract that no derogatory comments were to be made about any of the panel who in the first series eliminated her in the early stages.
"As she broke this we sadly had no choice but to sack her."
Ms Lennard's publicist has so far not responded to the Tiger Aspect statement.
