Indian police have registered a case accusing Bollywood actor Akshay Kumar and his wife of obscenity after she unbuttoned his jeans during a fashion show.

Mumbai police said they acted after a complaint was lodged against Kumar and Twinkle Khanna by a social campaigner who called the performance “vulgar and indecent.”

Kumar, a brand ambassador for Levi’s “Unbuttoned” range, was strutting down the catwalk last week when he stopped in front of his wife, who was seated in the audience, and asked her to undo his trousers.
