The 19-year-old – who is appearing in the latest series of the BBC dance show – says her famously foul-mouthed celebrity chef father will give his opinion on her dancing.
Tilly, who has starred in her own cooking show for CBBC, told Yahoo UK: "I think I'll take criticism pretty well. I do live with one of the harshest critics in my house – Dad.
"So I'm pretty used to that kind of stuff. He'll probably give his own criticism at times. But you need criticism to learn."
The star of MasterChef Junior US and Matilda And The Ramsay Bunch has enlisted her Hell's Kitchen star father into performing dances with her on TikTok, where she has 9.5m followers.
But Tilly does not believe her TikTok experience will give her any advantage in the competition.
She said: "I think TikTok is a very different style of dancing – a lot of the time it's not really dancing.
"Maybe it's helped me prepare in terms of learning a routine. But they are really very short clips and the good thing about them is it's not live – so you can do that as many times as you need to."
And Tilly confesses she is extremely clumsy and hates wearing high heels.
She said: "I would describe my dancing style as awkward, uncoordinated and clumsy. I'm a very clumsy person."
Tilly added: "I hate high heels. I wore some to my birthday party and they were off within five minutes. They were too painful. Since then, I've never really put them back on.
"Recently I've been trying to walk around the house in some hills and get used to them. But after a couple minutes, my feet hurt and my slippers come right back on. I'd love to be able to do the waltz in slippers!"
The BBC celebrity dance contest is due to begin on Saturday 18 September.
Also taking part this year are BBC Breakfast star Dan Walker, McFly's Tom Fletcher, Olympic swimmer Adam Peaty, EastEnders stars Nina Wadia and Rose Ayling-Ellis and former Bake Off winner John Whaite.
Judges Craig Revel Horwood, Motsi Mabuse and Shirley Ballas will be back, but Anton Du Beke will be filling in for Bruno Tonioli.
Tonioli is unable to take part because of the complications of travelling between the UK and the US, where he judges Dancing With The Stars, amid the COVID pandemic.
