Watch: Louis' Memory Lapse -- Live!
Heartthrob Louis Tomlinson forgets song lyrics during a One Direction show in Wales.
Talk about a show stopper.
"I just forgot the lyrics. I'm not even going to pretend that I know them," the One Direction singer admitted, trying to sing the part.
"I'm sorry, Cardiff," the 21-year-old said as the crowd cheered him on.
At a show in Glasgow, Scotland, a frenzied fan hurled a shoe onstage, which hit Styles square in the groin. Despite falling to the ground in pain, the 19-year-old mustered a smile and promptly got back to his feet after a few stretches.
The British boy band are currently in the U.K. leg of their tour, with upcoming performances in Dublin and Belfast, Ireland on Wednesday, Thursday and Friday.
Launch the video, above, to see Louis' on-stage fumble. Then tell us, Directioners: What has been your favorite moment of 1D's world tour so far? Are you going to a show this year?
