Good Morning Britain star gave a hint at the winner of BBC's Celebrity Traitors while presenting the ITV show. The 58-year-old, who is set to appear in the upcoming series, was grilled by her co-star on who might come out as the champion.

The exchange unfolded as it was 50th birthday today. Adil mentioned her celebrations, saying: "She hasn't told me about any party that you have planned, have you?" Kate teased: "She hasn't told you, Adil." He replied heartily, joking: "Ok, fair enough. I know my place!"

He added: "She's harsh. You can tell she was on that show, The Traitors. Honestly!" Kate laughed: "Stop it," before Adil grilled: "But did you win? Come on!" His co-star refused to answer as she turned away from him slightly and shook her head. She said: "I'm not even discussing it. Somebody in a cloak will take me away if I say anything!"

The charity spin-off of The Traitors is set to see 19 celebrities, who also include acclaimed actress Celia Imrie, comedian Alan Carr and singer Cat Burns, gather in the Scottish Highlands for the "ultimate game of deceit and betrayal".

Other stars joining the group at Ardross Castle are former England rugby player and podcaster Joe Marler, presenter Jonathan Ross, broadcaster Clare Balding and singer Paloma Faith. Actor and broadcaster Sir Stephen Fry, Olympian Tom Daley, singer Charlotte Church and TV presenter Kate Garraway are also among the names confirmed.

star Tameka Empson, Bafta award-winning film-maker and historian David Olusoga, and comedians Nick Mohammed and Joe Wilkinson are also part of the line-up, while influencer Niko Omilana, Scottish actor and Shetland star Mark Bonnar, Irish actress and The Midnight Club's Ruth Codd, and comedian and TV star Lucy Beaumont complete the line-up.

Just like in the normal series, host Claudia Winkleman will be at the helm. The nine-part celebrity version will give contestants the chance to win a cash prize of up to £100,000 for a charity of their choice.

The game show follows contestants as they try to detect the Traitors in the group while completing a series of challenges to win cash towards the prize pot. If at the end of the series a Traitor is among the finalists, the Faithfuls lose out on the money and the Traitor takes the full cash prize home.
