A concertgoer has sued Madonna following her Celebration World Tour show in LA on March 7 earlier this year.

The fan alleges that Madonna produced "pornography without warning" during the concert and says that he was forced to "watch topless women on stage simulating sex acts".

The plaintiff, Justen Lipeles, filed a lawsuit in a California court on Wednesday, making several allegations against the pop singer concerning her concert at the Kia Forum.

Lipeles bought the concert tickets for $500 (€460) each. While tickets stated that the concert would commence at 8:30 p.m, Lipeles claims that it instead took place at 10 p.m: "Defendants did not provide any notice to plaintiff that the concert would start at a later time."

The lawsuit also notes the high temperatures inside the venue: "The temperature inside the Kia Forum was uncomfortably hot as required by Madonna, who refused to allow the air conditioning to be turned on."

The plaintiff claims that due to these conditions, he was "profusely sweating and became physically ill." He states, "When fans complained about the heat, Madonna unreasonably told them to take their clothes off."

Lipeles's lawsuit also declares that Madonna was lip-syncing throughout the performance, and that he "felt like he was watching a pornographic film being made."

Lipeles is suing for breach of contract, negligent misrepresentation, unfair competition, false advertising and emotional distress, with the lawsuit stating that the 'Like A Virgin' singer's actions were "intentional, extreme and outrageous."

Lipeles has called for compensatory damages, legal costs and a refund for his concert tickets.

Both Madonna and the concert promoter, Live Nation, which was also identified as a defendant, have yet to publicly comment on the lawsuit.
