'I'm a Celebrity' star Helen Flanagan is to team up with her fellow jungle campmate Rosemary Shrager in a live festive edition of 'Who Wants To Be A Millionaire?'
Former 'Coronation Street' actress Flanagan, who was continually forced to face gruesome challenges down under, will be seen facing a grilling from Chris Tarrant on Thursday.
How Will Helen Flanagan fair on Who Wants To Be A Millionaire?
Also appearing in the Christmas edition will be JLS stars JB Gill - who appears on a 'Strictly Come Dancing' special next week - and Oritse Williams.
Veteran entertainer Des O'Connor will pair up with comic Lee Mack for the show, aiming to win cash for charity.
Helen said: "It should be great fun and I love the show. I have watched it since I was little and it's legendary."
Lee - who stars in BBC1's 'Not Going Out' - said: "I'm playing for The Donna Louise Children's Hospice Trust, and with Des's brains and my looks, we're doomed."
The celebrities will be battling against the clock when they take part in the live programme, which will also see a viewer attempting to share in the cash.
The hour-long show will be screened at 9pm on ITV1 on Thursday.
