Jesy Nelson
No Time For Tears was the group's final single before Jesy Nelson quit in 2020.
"You can’t control how things go," Perrie said of her Little Mix bandmate.
"I can’t even listen to without crying," the former Little Mix star revealed.
“It was a complex and painful thing to come to terms with,” Leigh-Anne Pinnock has said in her new memoir.
Torvill and Dean will be putting stars from across the world of music, sport and TV through thier paces next year.
Jesy said she thought it was "f***ing bulls**t" that the media had focussed more on her comments about Little Mix than the themes of domestic violence in her new single.
While Jesy's departure from the pop group was initially said to be amicable, that's not exactly how things turned out.
The Great Celebrity Bake Off line-up also includes an Olympic gold medallist, comedy greats and a Loose Women fave.
Both parties have confirmed they are no longer working together.
The Sun previously reported Jesy's album had been delayed after "early versions of her new tracks failed to impress record label bosses".
