Tonioli, who judged Strictly Come Dancing alongside Revel Horwood until 2019, is the latest star rumoured to be taking over from David Walliams on the BGT panel.

Walliams is said to not be returning to his role after 10 years with the ITV show over insulting comments he was overheard making about a contestant, and comedian Alan Carr has also been rumoured to be in the running for the panel.
Speaking on Good Morning Britain, Revel Horwood said: "I would love to see Bruno back on our screens and I think it’s a great position to have so I wish him all the very best if he is in the running for it because I think he’d be wonderful to get that energy back on the telly."
But the TV star made it clear he did not know for sure who had landed the job.
He said: "I would love to say he is [the new BGT judge] but I believe he’s up against Alan Carr as well so I think they’re juggling and they’re going to save it as a surprise, so I in fact don’t know.
"And Bruno is very secretive with me, darling, so he will never be honest with me or tell me the truth. So I really don’t know."
Tonioli was unable to join Strictly as a judge during the Covid pandemic as he usually travels for work between the US and UK, and Anton Du Beke was confirmed last year as his permanent replacement on the dance show.
Britain's Got Talent has signed up a former BBC star for the ITV show before - long-serving judge Alesha Dixon moved to the contest from her judging role on Strictly, where she worked with Tonioli.
