The Crown star Greg Wise and TV presenter and influencer Matilda 'Tilly' Ramsay have joined the line-up of Strictly Come Dancing.
Wise, the husband of fellow actor Emma Thompson, said he was taking part in the series as a tribute to his late sister.
"My beautiful sister was a huge disco queen," said the 55-year-old. "She left our world almost exactly five years ago in a glitter ball coffin.
"I will channel her, as her bro can't dance - but I'm thrilled to be dipping my toes, knees, hips and arms into this wonderful world, and hope to make her proud, and obviously make her laugh..."
Tilly Ramsay, 19, who is the daughter of chef Gordon Ramsay and his wife Tana, is best known for presenting cooking show Matilda and the Ramsay Bunch on CBBC alongside her family.
She and Wise join the previously announced line-up of TV presenter AJ Odudu, Peep Show's Robert Webb, McFly star Tom Fletcher, Dragons' Den investor Sara Davies, Coronation Street star Katie McGlynn and BBC Breakfast presenter Dan Walker.
CBBC host Rhys Stephenson and former Bake Off winner John Whaite will also take to the dancefloor in the BBC One series, with Whaite set to compete as part of the show's first all-male pairing.
Ramsay, who has more than 9.5 million followers on TikTok, where she regularly posts videos of herself with her father, said: "I'm so excited and grateful to be joining the Strictly family!
"I'm always up for fun, new challenges and this will be my biggest adventure yet! I'm going to put my heart and soul into this and can't wait to get my dancing shoes on and show my dad how it's really done!
"Bring on the glitz, glamour and sequins!"
