Lady Gaga was forced to halt the final show of her Chromatica Ball tour in Florida after a fierce storm descended.

The star was approaching the end of her show when lightning started to strike around Miami's Hard Rock Stadium.

"We just got to stop the show for a minute," she told the 65,000 fans at the show, advising them to "really calmly move to the inside area".

Although she had hoped the storm would pass, the concert ultimately had to be called off.

The star later posted a tearful apology to fans on her Instagram account.

"We really tried to finish the show tonight in Miami but we couldn't because even when the rain stopped there was lightning striking right down to the ground so close to us," she said, still wearing her stage outfit, and wiping rain from her face.

"I don't know what I would do if anything happened to anybody in the audience or to any member of my crew," she added.

The singer then picked up a bouquet of roses that a fan had tossed onto the stage and said she would "cherish them forever".

The Hard Rock Stadium is home to American football team Miami Dolphins and only has a partial roof.

Before the show was cancelled, fans gathered under the sheltered portion of the venue and sang Gaga's hit Rain On Me - punctuated by terrifying claps of thunder.

Although they later made their way back to their seats, organisers decided it was unsafe for the concert to go ahead.

Gaga, who had about six songs left to perform, took to the stage to announce the cancellation, saying: "I don't want to put your life in danger. Get home safely, God bless you and thank you for coming to the show," she said, before taking a final bow.

Fans who attended the show said Gaga was "clearly upset" by the cancellation.

"It was surreal and really sad when she came out and told us to go home. You could tell how heartbroken she was," wrote one on Reddit.

The Hard Rock stadium posted a statement on Twitter, reading: "Tonight's Lady Gaga show couldn't continue after a show pause at 10:50 pm in the interest of fan safety due to inclement weather that included lighting. Thank you for your understanding."

The Chromatica Ball tour began in Dusseldorf, Germany, in July before visiting Sweden, France, the Netherlands, the UK, Japan and North America.

With a setlist including Bad Romance, Poker Face, Born This Way, Edge Of Glory and Stupid Love, the show has won rave reviews for its combination of dramatic set-pieces and a running narrative about surviving trauma.

The Guardian called it a "hit-stacked show that also creates an intimate human connection"; while Rolling Stone magazine said it served as "a reminder that she's one of the greatest living musical performers".

The tour was confined to just 20 shows, with several rest days between concerts to help Gaga cope with the medical condition fibromyalgia.

The condition often leaves her in chronic pain, and resulted in the cancellation of the last 10 dates of her previous world tour in 2018.

"It took so much in my heart to get back to a place where I could perform and be healthy," she said on Instagram after the Miami concert.

"Part of why I decided not to finish the show was because I am healthy. It's a healthy decision for all of you and for myself as well. So I love you... and I'll see you next time on stage," she added. (BBC)
