Chantelle Houghton says her first stint in the Big Brother house back in 2006 was "a once-in-a-lifetime" experience but she'd jump at the chance to go back in.The iconic reality show - which launched the careers of the likes of Alison Hammond and Josie Gibson - is set to return to screens later this year, five years after it last aired on Channel 5. Chantelle, who bluffed her way to victory in the Celebrity version of the show by pretending to be a famous pop singer, says it was the thing that turned her life around and she'd love to have another go. “Definitely, without a shadow of a doubt, it’s such a great experience,” she says.
