BIG Brother favourite Skye Wheatley isn't faking her ditzy persona, says intruder Richard Hordern-Gibbings.
The 25-year-old, who was evicted from the show last night, insists all of the housemates are being genuine.
"She's not faking it," he told APN.
"Skye is a born performer. Whenever the conversation wasn't revolving around her, she did love to walk off and sing to the mirrors or just start talking to herself. I wouldn't call that usual behavior on the outside.
"But I've got to make this really clear, everyone in the house is completely genuine."
Viewers jumped at the chance to evict two intruders this week, with Tom Mackay going home on Monday night.
Richard said bubbly dancer Penny Higgs has a shot at competing with the more established original housemates.
"If Penny and Lina can hang out a bit longer, then I'd love to see one of them get through to the finale," he said.
"Penny is highly entertaining and she is like that 24 hours a day. She's as mad as a cut snake. If she can't win as an intruder then no one can.
"She's the only person (from the house) I'd watch if they had their own spin-off show."
The Sydney bank teller, who bears a striking resemblance to Harry Potter star Daniel Radcliffe, believes things will soon get nasty between the remaining housemates as the grand final approaches.
"They're all still pretending to be best friends but they've all got an agenda," he said.
"They all want the money. They're that close they can almost taste it. The next couple of weeks it's going to open up really quickly and everyone will come crashing to earth."
The housemates will watch on tonight as their family and friends cast votes for eviction nominations.
