The new series of the BBC ballroom show saw the Kiss FM DJ and professional partner Dianne Buswell perform an American Smooth to Falling by Harry Styles as the 15 latest stars all took to the floor for the first time.
During the routine, they attempted the challenging Angel Lift, which saw Tyler lift and spin Dianne over his head.
Shirley praised the couple for their lift, saying “any girl would feel safe doing any kind of tricks” with Tyler, but when it came to giving her score, there was some confusion.
As the judges were called to reveal their marks, Shirley could be seen still scrambling to find the correct paddle, before she remarked: “I’m putting up a 7.”
However, a score of 6 – which Shirley would have entered into her electronic keypad prior to revealing her score – appeared on screen, leading to some confusion.
Host Claudia Winkleman remarked: “OK, we just need to clarify because Shirley held up a 7. I’d imagine you’d prefer a 7…”
Confirming she was awarding a 7, she said: “I got muddled up with my paddles. I was in a bit of a muddle.”
The first week’s scores only tell half the story though, as next Saturday, the couples will take to the floor once again, with their totals from across the two weeks combined. One couple will then become the first to be voted off this year’s show.
Strictly Come Dancing continues on Saturday at 6.30pm on BBC One.
