Rex and Rachel argue over Nicole

The rocky friendship of Rex and Rachel suffered another blip last night.

Trouble started when he asked her why she had chosen to nominate the chef.

"I nominated you because of the way you were with Nicole, for the way you treated people, the way you treated me," Rachel explained.

"What do you mean the way I was with Nicole?" he asked.

"When she was in the house, you were not a very nice person," she answered.

She added that the way Rex spoke to Kat sometimes was also a problem.

Annoyed by Rachel's explanation, Rex countered by contrasting the pair's 'real' and 'fake' behaviour.

"I'm not fucking fake all day, skipping around the fucking clouds going 'la la la la la la la'. I'm real. I have my ups and I have my downs. The way you deal with things is by agreeing with everyone."
