“We learned about this alleged threat via media reports this morning,” a spokesperson for the singer shared in a statement with The Hollywood Reporter. “Prior to and during the show, there were no known safety concerns, nor any communication from the police or authorities to Lady Gaga regarding any potential risks.

Her team worked closely with law enforcement throughout the planning and execution of the concert and all parties were confident in the safety measures in place.”

Lady Gaga’s biggest show of her career, drawing more than 2 million people to Copacabana Beach in Rio de Janeiro, police in Brazil said they worked with the Justice Ministry on an operation to stop an alleged attack planned by a group that was spreading hate speech against the LGBTQ community.

According to authorities, the group sought to radicalize and recruit teens to carry out attacks using Molotov cocktails and improvised explosives. “The plan was treated as a ‘collective challenge’ with the aim of gaining notoriety on social media,” police said.

On Sunday, after the concert, Lady Gaga took to her Instagram to praise her fans, also known as “Little Monsters,” for the unforgettable night.

“Nothing could prepare me for the feeling I had during last night’s show — the absolute pride and joy I felt singing for the people of Brazil,” she wrote in part. “The sight of the crowd during my opening songs took my breath away. Your heart shines so bright, your culture is so vibrant and special, I hope you know how grateful I am to have shared this historical moment with you.”
