Kate Garraway has revealed that last night's episode of The Celebrity Traitors left her 'mortified' as she discovered what her co-stars had been saying about her. The BBC One spin-off kicked off last night, with 19 stars arriving at the iconic Scottish castle to play the popular game. Hosted by Claudia Winkleman , the show sees the likes of Jonathan Ross, Alan Carr, Charlotte Church, Cat Burns, Tom Daley, Celia Imrie and other stars attempt to win up to £100,000 for their selected charity.
