Security guard mistakes drag queen for Lady Gaga on her Chromatica tour

Viewers can't quite understand how a security guard accidentally mistook a drag queen for Lady Gaga.

Viral footage shows lookalike walking through a busy corridor of people, until she is stopped by the officer.

Watch the incident unfold below:

As the drag queen briefly squares up against the guard, she defends herself by saying: "I'm a drag queen. I'm a drag queen.

The fact she had to shout it out loud – that she isn't the 'Poker Face' singer – suggests just how perplexed the security guard was.

One person joked: "I would’ve ran with it. Gotten on the tour bus & everything."

Another added: "LMFAOOOOOOOOO this is the funniest s**t to ever exist."

"Saving this for future references," a third person quipped.

Someone else said: "Me personally i wouldn’t take that," while another added: "He had one job."

During her show, the singer was forced to stop mid-way through, and later posted a tearful explanation video on Instagram.

Gaga told her 50 million followers that an unforeseen storm had shut the show down, and lightning strikes sparked concern for the safety of her crew and fans. 

During the show, Gaga said: "We just got to stop the show for a minute," before advising them to ‘really calmly move to the inside area’.

Gaga later explained: “Hi everybody. Thank you so much for coming to the Chromatica Ball. We really tried to finish the show tonight in Miami, but we really couldn't, because even when the rain stopped, there was lightning that was striking down to the ground so close to us.”

She added: “I know that for a really long time I’ve always wanted to be, like, that hardcore bad b***h, but what I also want is to be responsible and loving and I don't know what I would do if anything happened to anyone in the audience or any members of my crew, so I'm sorry that we didn't get to do the epic version of 'Rain On Me'.”

Holding up flowers that a fan had thrown onstage, Gaga noted: “Whoever threw these to me onstage I will cherish them forever."

“I don't want to put your life in danger. What’s worth it more to me is life,” she added before signing off her video saying: “Get home safely, God bless you and thank you for coming to the show.”
