Harry Styles Helps Fans Reveal Sex of Their Baby on Stage at His Concert

A couple in London went all out to find out if they are having a girl or a boy — and tapped Harry Styles for the big reveal.

In a video captured by a fan on Twitter, Styles was performing at Wembley Stadium in the U.K. for his Love on Tour concert series. He is seen holding up a black balloon with the words "Boy or girl?" written on it as he amps up the crowd for the big moment.

He asks the couple, "What do you want?" as he paces around the stage.

Teasing the audience, he jokes, "I'm not sure I'm ready. I don't know if I'm ready!"

In another clip, he pops the balloon with a pin, and pink confetti pours out. The reveal is met with cheers in the arena, which seats 90,000.

This isn't the first time in recent days that a star has helped fans with a life-changing moment while on stage.

Last month, Katy Perry let one fan propose to his boyfriend during a show for her PLAY residency in Las Vegas.

"They just told me backstage that the guy in the stripes wanted to ask his boyfriend to get married," said Perry. "And since it's the last show, you guys are the best, congratulations."

After she stood up while the couple embraced, the "Roar" singer joked, "I'm PMSing so it's more than I should be."
