Here's a look at the rather surreal advert for Britain's Got Talent 2013 being filmed in London.
BGT 2013 hosts Ant and Dec were on set in Covent Gardens for filming of the promo, which also saw past stars of the show reunite.
Amongst the various performers involved were last year's winners Ashleigh and Pudsey, as well as former winners Spelbound.
Former runners up Twist and Pulse were also taking part, as well as Stavros Flatley and circus performer Billy George.
The ad sees members of the public press a large blue button before being surprised by the appearance of Ant and Dec together with a flashmob of the BGT stars past and present.
The upcoming series of Britain's Got Talent 2013 doesn't have a start date yet, but based on previous years will probably premiere in April.
Auditions for the show are still taking place, although will conclude this weekend in Birmingham.
The judges - Simon Cowell, David Walliams, Alesha Dixon and Amanda Holden - have already visited London, Cardiff, Glasgow and Manchester on the hunt for talent.
