Len Goodman has warned his fellow 'Strictly Come Dancing' judge Bruno Tonioli.
The 72-year-old head judge has reportedly had words with the Italian dance enthusiast about knocking him with his flamboyant hand gestures whilst giving feedback to contestants on the BBC One latin and ballroom show.
An insider told The Sun newspaper: "There have been several times this series when Bruno has clonked Len in the face. But it was the final straw on Saturday after several incidents involving Bruno's wild arms and Len decided to confront him about it.
"Len told Bruno to control himself and to stop bashing into him in an exchange off camera. Len knows it's just Bruno's bonkers personality but he thinks he could end up with a black eye."
On the show on Saturday (08.10.16), Bruno was seen bashing into Len on several occasion including while he was talking to contestant Will Young and his dance partner Karen Clifton.
According to the publication, Len - who has sat next to Bruno on the panel since the show's debut in 2004 - was overheard grumbling before judge Darcey Bussell safeguarded him.
It comes just a week after Bruno stormed out of the studio in protest over last Sunday's (02.10.16) results show.
The fiery star was said to be furious with the decision by producers to axe the dance-off and eliminate Melvin Odoom when Anastacia was unable to perform and he allegedly fled to his car and demanded to be taken home.
At the time, a source said: "The studio audience had no idea about the backstage drama."
However, Bruno soon calmed down and took his place on the panel alongside the other judges as Melvin was eliminated.
