At a recent show, a drag queen dressed as Lady Gaga inadvertently fooled fans in a crowded concourse AND a security guard. She finally had to announce, multiple times, "I'm not Lady Gaga! I'm a drag queen."
The security guard in the video was clearly dismayed. There's some salty language so we can't embed the video but you can find it here.
Meanwhile, the real Gaga was tearful on Instagram after having to cut her show in Miami short due to severe weather. She was sad about it but concerned for everyone's safety.
