Conspiracy theories about 'Pauline' have been doing the rounds since the fake Aussie housemate entered the House yesterday. If you've been watching closely you'll even have seen some serious chin scratching.

In a discreet bedroom chat last night, Tracey flagged up her doubts to Carole, dwelling on the new arrival's appearance following a supposedly long haul trip from Australia.

"She hasn't got any make-up on," stated the raver, provoking an instant response.

"If she's been on a flight for 24 hours..." began the 53-year-old, quickly gathering speed, "I don't think she'd go into a new House without making sure she's got some make-up on. And her hair doesn't look right."

"It looked like it was contrived in some way," concluded Carole, firmly onto the scent.

"It is too odd," chipped in Tracey.

An hour later Charley was hot on the case. Sitting in the garden alongside Nicky and Tracey, she mused: "I think she does know a little bit about us... trust me - there's gonna be a big catch."

It looks like 'Pauline' has a hard job ahead of her if she's to avoid being rumbled so soon after entering the House...
