Strictly pro AJ Pritchard has told Newsround that he doesn't think that judges should ever be able to award 10s in the ballroom.
It's always a big moment when a celeb gets their first 10 on Strictly Come Dancing.
This year, actor Kelvin Fletcher was the first famous face of the series to bag a perfect score for his Charleston with partner Oti Mabuse during Movie Week.
But AJ told Newsround that a perfect score "should never happen" and that the top mark should only ever be 9.5 as there's "always room for improvement".
We put AJ's suggestion to Strictly Come Dancing to see what the judges thought about his comments, but they declined to comment.
Should the judges be able to give the dances full marks? Should we see 10s on the judging panel?
