A new Big Brother housemate is to be chosen from 35 people who found golden tickets hidden in chocolate bars.

The winner will be chosen at random by the housemates in a live lottery draw on Channel 4 at 2200 BST on Friday.
Ticket holders include a tennis player, a grandmother and a woman who claims she bought 13,000 bars in a bid to win.
The tickets were hidden inside special Kit Kat bars in a unique competition to find a member of the public to join the contestants on the reality TV show.
Winners include Tim Slessor, 28, an audio visual editor from London, who claimed the first golden ticket.
Sue Carter, 34, found her ticket after buying 13,000 Kit Kats in a radio promotion.
Grandmother Su Lindsey, 50, would be the oldest person ever to take part in Big Brother if she is selected.
Also on the list is professional gambler and journalist Ed Murray, 28, former internet stripper Matt Oakes, 22, from Coventry, and 25-year-old self-proclaimed playboy Mohammed 'Nad' Butt, from London.
Philip Colaco, 21, from Dundee, Deby Dakers, 25, from Norwich, and unemployed Martyn Hilliard, 23, from Market Harborough, are among several of the hopefuls who bought their tickets on an internet auction site.

A total of 100 tickets were hidden in Kit Kat bars and distributed around the UK.
Of those tickets, 58 were found before last Friday's deadline, but two people decided not to put themselves forward for the show, two dropped out, and 19 did not pass the required background checks.
A Big Brother spokesman said: "We are delighted that 35 Golden Ticket holders will have a chance of entering the Big Brother house.
"The response to the competition has been incredible and we have been amazed that so many people are able to drop everything to become a housemate."
Meanwhile, unemployed nail technician Sam Brodie was evicted from the Big Brother house on Friday, leaving other nominee Nikki Grahame for another week.
Sam, 19, from Irvine, had been favourite to be evicted.
