Harry Styles is now the most important thing about Kelly Clarkson’s first Las Vegas engagement.

Kelly began her stay by singing the hit song “As It Was” by Harry.

After starting her show, she sang a medley of her most popular songs: Stronger, Since U Been Gone, and Because of You.

But she was meant to sing his song on The Kelly Clarkson Show, her daytime show, but she couldn’t because of the Hollywood strike.

Before she started her performance, the 41-year-old singer said that she was going to sing the song by the former One Direction members during the Kellyoke part of her show, but that the SAG-AFTRA strikes made that impossible.

She told People Magazine, “We’re gonna go a little Kellyoke every night. We were supposed to sing this actually on The Kelly Clarkson Show, and then all the strikes happened and nobody has a job now, so we didn’t get to perform it on the show.”

The singer of “Piece by Piece” has just started her residency, while Harry Styles just finished his two-year Love on Tour on an emotional note in Italy last week.

Harry Styles thanked his fans for coming to his shows with their hearts and minds full of excitement. He said that his tour was the best thing he had ever done.
