BB7's SusieSusieThings aren't looking so glittery for Big Brother as claims that the Golden Ticket contest was rigged are being taken seriously.

One hundred tickets for the competition were hidden inside KitKat bars, which resulted in Susie Verrico entering the house.

Since then the Advertising Standards Authority (ASA) has received five complaints suggesting that the draw was fixed and Susie was pre-selected. It is now investigating both Channel 4 and Nestle about the promotion.

When the 43-year-old model entered the house she was recognised by several housemates and it emerged she'd auditioned for the show several times.

Big Brother boss Phil Edgar-Jones has said: "There is absolutely no truth in any of the rumours that the Golden Ticket draw was a fix."

A Nestle spokeswoman said: "We are fully assisting the ASA in their investigation. We look forward to a speedy conclusion."

And a Channel 4 spokesman said: "We will provide them with information to prove there is no truth in any of the golden ticket fix allegations."
