The 19-year-old singer, who was the best man at his mother Anne Cox's wedding, suffered a stage fright while presenting a speech in front of just 100 people at restaurant in England, reported Showbizspy.
"I did give a speech and I can honestly say it was the most nerve-wracking thing I've ever done. I practised on my own for days beforehand, on the sofa reciting it to myself. I tried to make it have a bit of everything," Styles said.
