I completely agree and I'm not much older than her!
She comes across absolutely terribly. Attention-seeking and wanting the limelight despite having zero actual talent. Her screeching was doing my head in and demanding Nigel do countdowns for her in the eating trial was so OTT, it was clear she's a total drama llama.
Then the thing with Fred. Playing the victim, feeling "triggered". He did absolutely nothing wrong apart from say he's old enough to be her dad. Which he is and it's an expression. You could see he was totally blindsided and he tried to apologise but she just kept going and going. I'm amazed he managed not to totally laugh in her face it was the most OTT ridiculous reaction. And ignoring him when he was speaking to her.....like a toddler.
She isn't "just a girl." She is a grown adult woman, clearly she hadn't learned to behave like one.
