Renowned physicist Professor Stephen Hawking is the latest celebrity to silence the Go Compare advert singer, by sucking the opera singer into a black hole.
The former Lucasian professor of mathematics at Cambridge University is the next celebrity to star in the website's adverts, where well-known figures plot to destroy fictitious singer Gio Compario.
The advert, which will be shown for the first time today, sees the 70-year-old Hawking to announce to a packed lecture theatre that he has discovered how to generate a super massive black hole, in which the singer gets sucked into.
Professor Hawking said: "I confess I am a fan of the Gocompare.com adverts, but I am also an opera fan, so I was delighted to be given the opportunity to help save the nation and silence Gio. I hope the public find it as funny as I did."
