One Direction kicked off the North American leg of its On the Road Again world tour Thursday night in San Diego, Calif. It was the boy band's first American concert since Zayn Malik quit the group in March.
When Niall Horan, Liam Payne, Harry Styles and Louis Tomlinson were performing "Through the Dark," Styles dragged his microphone and fell backwards. While still on the ground, he laughed at the incident.
Without mentioning Styles' slip-up, Horan tweeted about the show. "San Diego! U were badass! The stadium was one of the best I've ever seen, the crowd was insane! Loved every minute of it," he wrote.
