Watch: Alesha Dixon discusses Bruno Tonioli's approach to BGT
Former Strictly star Tonioli has joined the panel alongside Dixon, Amanda Holden and Simon Cowell after the departure of David Walliams, who left the line-up after it emerged that he had made insulting comments about contestants.
There have already been rumours about the dancer causing a lot of laughs on set with his hilarious antics, and Dixon was quizzed about it when she appeared on ITV's Lorraine.
Laughing, the TV star admitted: "I have a few Bruno bruises as I like to call them - he likes to grab the arm!"
"I don't think he's got the rules yet, no!" she told presenter Lorraine Kelly.
"I think after day two we just turned to each other and said, 'Let's just throw the rule book away!'"
Dixon added that for Britain's Got Talent it was "the era of anything goes".
Tonioli had been on BBC ballroom show Strictly since it launched in 2004.
He left in 2022 and former pro Anton Du Beke took over his seat on the panel.
Walliams was at the centre of a controversy last year when the Guardian reported that he had been overheard making insulting comments about some of those auditioning while on the BGT set.
He apologised for his “disrespectful comments”, saying that they were part of private conversations that were never meant to be shared but that he was sorry.
The comedian had been on the panel of the programme for 10 years.
