Justin Bieber appeared to blow his nose on a fan's hoodie during his performance at London's British Summer Time festival in Hyde Park.
According to The Sun, Bieber left fans disappointed after he slowed his performance down with a number of bizarre rants, telling the audience he had a bad cold.
Halfway through the performance, the singer told the crowd he had used a Vicks inhaler and that "all that medicine stuff is stuck in my nose".
"I'm having a rough night. Don't judge me," he told the crowd.
Footage on The Sun shows Bieber then proceeding to take what looks like a fan's hoodie and blowing his nose on it.
