Around 40 people complained about Fabia Cerra's performance
Dozens of people have complained to the broadcasting watchdog after a burlesque dancer stripped down to nipple tassels and a basque on Britain's Got Talent.
Ofcom said it had received 39 complaints about ITV1's show - aired at 19.45 BST on Saturday - in which Fabia Cerra, 35, removed her clothes.
ITV said it had considered broadcasting the performance carefully and had obscured "inappropriate detail".
Ofcom is examining the show to see if a full investigation is needed.
A spokesman for ITV said: "Fabia's performance was given careful consideration by ITV, the producers Talkback Thames and the licensee Channel Television.
"As a result, the segment was edited in order to obscure any inappropriate detail, and it was felt that the overall effect was comedic rather than titillating."
It is understood ITV received about 40 complaints about the Oxford housewife's performance. The show's peak audience was 11.8 million.
A 47-year-old church volunteer from West Lothian has become an unlikely overnight singing sensation after her appearance on the same show on Saturday.
Susan Boyle, from Blackburn, stunned judges with her performance of I Dreamed A Dream from Les Miserables.
