Justin Bieber told a crowd on Sunday night that he is battling cold symptoms.
“I’m having a bad night,” the Canadian pop star said at the British Summer Time festival in London’s Hyde Park.
“Don’t judge me.”
The Daily Mail reported that Bieber gave a “shaky performance” while the BBC noted his “low energy levels.”
At one point, Bieber talked about having nostrils full of “medicine” — specifically Vicks.
As he usually does in concert, Bieber lip-synced several songs. But fans noticed that he messed up the words to “Love Yourself” and even snapped at his backup singers for talking between songs.
“Whatever you’re talking about can’t be more important than what I’m saying,” he said.
Bieber will have plenty of time to recover from his cold. His Purpose tour is on a break until July 29, when it returns to North America. He’s set to play two shows at the Rogers Centre in Toronto on Sept. 5 and 6.
