Strictly Come Dancing judge Anton Du Beke once 'stole' Shirley Ballas' underwear and used it to 'wipe his forehead'.
Head judge Shirley, 62, made an appearance on The Jonathan Ross Show where she discussed all things Strictly.
She was joined by Jeff Goldblum, comedians Lee Mack and Jack Whitehall and John Legend.
The Strictly crew only recently finished their live tour after a fantastic season which saw Hamza Yassin & Jowita Przystał win the Glitterball trophy.
Speaking about touring recently with the show, Shirley told Jonathan: "It was an amazing experience.
"Anton Du Beke was on it this time - that man is so funny. He comes across as the perfect gentleman, but he’s very naughty behind the scenes."
She continued: "He came to my dressing room [and] I had my big girl Marks & Spencer knickers out.
"The next thing I know, we’re on set and he pulled them out of his top pocket and started to wipe his head with them… good job they were clean, eh?"
Shirley was also asked about the rumours that she isn't returning to the popular dance competition.
"Well… I do believe it’s in the process. Is that the right way to say it? Yes.. their people are talking to my people," she said.
In recent weeks, Shirley opened up about the suggestions she may not return to Strictly following horrific online trolling.
The 62-year-old dance professional was asked whether she would be returning to the show when she appeared on a recent edition of This Morning.
Sitting on the famous blue sofa to talk about her new romance book, Murder on the Dance Floor, Shirley was asked about the upcoming season by host Holly Willoughby : "You're not thinking of not being there?"
Shirley didn’t confirm or deny the rumours, instead revealing she was waiting for her invitation to return to the show.
She said: "Well, we're waiting for that invitation and once it gets there and we sort out... I love the job, I love the actual critiquing.
“I love to get tips and help people along the way, to move forward to be beautiful dancers and all that they can be."
