Kate Silverton will present Channel 5's 'Help The Animals At Christmas' show this year.
The 48-year-old BBC News presenter will host the festive show, which will raise funds for the RSPCA, Scottish SPCA, Blue Cross, the Donkey Sanctuary and Wildlife Aid foundation.
Ben Frow - the director of programming at Channel 5 - said: "Christmas should be a happy time for all, including those who don't have a voice - animals.
So this year, along with a host of famous faces, we are going to shine a light on animal welfare, raising awareness and money for five animal charities who work tirelessly to bring comfort and joy to animals all over the UK."
Kate - who is currently competing on this year's season of 'Strictly' with dance partner Aljaz Skorjanec - will join fellow contestants Susan Calman, Gethin Jones, Gaby Roslin and Michael Underwood in the three-hour live appeal on December 21.
The BBC journalist - who tore a muscle in her rib a day before her performance last week - performed the Argentine Tango and failed to impress the judges who gave the dance pair low scores.
Before the performance, Kate spoke about her injury to Claudia Winkleman and detailed how the accident happened when she was practising lifts.
She said: "I stripped a muscle on the ribs.
It happened very late yesterday during training when we were doing a lift.
I've not had much chance to recover."
But even so, Shirley Ballas described the dance as "laboured" - causing 'Strictly' viewers to take to Twitter and brand the judges "unfair" for not accounting Kate's injury.
Kate and Alijaz are currently rehearsing a quickstep routine to 'I Want You To Want Me' by Letters To Cleo which they will perform on Saturday (10.11.18).
