Sydney Devereaux is the latest to join the Survival Of The Fittest cast in tonight's episode.
She replaced Lottie James, who was eliminated last night.
The Boys won the latest challenge on Sunday night, and it gave them the power to decide which two Girls had to fight for survival.
They put forward Lottie and Georgia Cole, who on monday faced the Survival Challenge.
And it was Lottie who was eliminated from the competition after losing the challenge to Georgia, who kept her place.
This evening's episode sees Sydney join. She is a 24-year-old Casino Croupier from Essex.
Ahead of entering, Sydney said: "Watching the show, I can see there is no one in there like me. I’m quite mischievous, energetic, bubbly. I’m very flirtatious.
"If I don’t fancy you, I can make you feel like the best person in the world. If I fancy you, I’m not as nice. It does mean I can lead people on the wrong way sometimes."
She continued: "The thought of being in South Africa amongst all of these amazing animals, and uniting as a team is really appealing to me. The Boys are really solid, even when they lose they are uplifting each other.
"Whereas with the Girls, they are more fickle and there are cracks in the team and my plan is to cement the cracks."
"I am fast and I’m very determined. I will keep going and I will not give up. And my support and my ability to pull people closer together will be good for the Girls team," she added.
Survival of the Fittest airs tonight at 9pm on ITV2
