Cheryl thinks Oti Mabuse is "way too competitive".
The "Love Made Me Do It" singer "loves" her fellow "Greatest Dancer" judge but claims the "Strictly Come Dancing" professional has been "stealing acts" from her and fellow panellist Matthew Morrison because she's so determined to win.
She said: "I love Oti. But she is way more competitive than me.
"She was the one stealing acts off of the table and hiding them from us.
"The thing is, she is so cute she gets away with it.
"Me and Mathew loved more of the same people and fought it out more to be honest."
Cheryl - who has 22-month-old son Bear with ex-boyfriend Liam Payne - has been very impressed by the talent on "The Greatest Dancer" and would happily use some of the acts in her own concerts and music videos - even those who haven't made it through to the live stages of the competition.
She told The Sun Online: "I would use so many of the people we have seen in my performances, shows and videos, definitely,
"And not just the ones that made it to the live stages but also people who didn't. There are so many talented people we've seen that have a lot to offer."
And the 35-year-old singer - who shot to fame when she competed on "Popstars: The Rivals" and landed a place in Girls Aloud - also shared the tips she's been passing on to the acts she mentors in the competition.
She said: "How you feel shows in your eyes and expressions. So if you are unsure of your performance others will feel it.
"You have to be comfortable in what you're doing and dance like no one is watching. The last bit sounds cliche but it's so true!"
