Strictly Come Dancing 2012 professional Flavia Cacace is said to be angry with her Olympic silver medallist Louis Smith over his 'lazy' effort in training.
According to The Sun, the 33-year-old Italian dancer was 'delighted' to land the gymnast, having been paired with astrologer Russell Grant last year.
But Louis apparently hasn't been pulling his weight during rehearsals - leaving Flavia feeling rather frustrated.
A show source commented: "Louis is used to a rigorous training schedule and Flavia expected him to be raring to go. He seems to be treating this like a holiday. It’s frustrating because she knows he has potential.
"Russell wasn’t the best dancer but you couldn’t fault him for effort. Louis should take a leaf out of his book."
Louis and Flavia will perform to the nation for the first time during tonight's live show at 6.30pm on BBC One.
