Former Big Brother finalist, Imogen Thomas, has hit out at Rex Newmark’s bullying behaviour and said his tirade against Rachel has to stop.

Yesterday Rex attacked Rachel after Big brother let some of the heavenly housemates watch her audition video.

He accused her of not being real and said: “You were a sexy bitch. But in reality, I’d swap you for Scrabble.”

Imogen told The Sun: “Just because she hasn’t made herself the centre of attention doesn’t mean she’s a liar.

“Rex is just being a bully and picking on her because he’s bored and has nothing to do.

“Rach is always really bubbly, sexy and confident. I don’t care what Rex thinks, whoever you are in your audition video is who you are.”

But Imogen feels Rachel’s real personality will shine through as the show enters its closing stages: “It takes some girls a while to show their real self, especially when you’ve never left Wales.

“As the numbers went down I became myself so much more.”
