Exclusive: Justin Bieber blows nose on fan's t-shirt

Justin Bieber has done what he does best, going on a bizarre rant during his perfomance at the British Summer Time festival.

The 23-year-old said "Sorry" for his "bad night", telling the London crowd he was suffering from a head cold as he took to the stage in front of 50,000 fans at Hyde Park. Watch the video above.

Stopping mid-way through his set, Biebs started a particularly enthralling conversation about Vicks VapoRub, saying he had been using the inhaler backstage to try and clear his nose, but was more used to another remedy called Olbas oil, according to The Sun.

Taking inspiration from his own songs, Justin then told his fans that "Life is worth living without Vicks in your nose" as he complained about the smell being stuck in his sinuses.

At one point the Canadian popstar went to blow his nose on a towel, but thought twice about throwing the used, and snotty, make-shift tissue into the crowd.

"I have a cold. You don’t want to catch this," he said much to the disappointment of his Beliebers.

Justin had pulled out of another massive gig in London over the weekend, however the Purpose hitmaker pushed through the two-hour set at the festival, despite struggling to sing, and his voice cracking at certain points.

The star's frustration was visible as he addressed his squad of back-up dancers directly after the caught them chatting while he was speaking to the crowd.

"What are you talking about that is more important than what I’m saying?" he could be heard asking them, according to the publication.

The Sun adds JB then launched into his break-out hit "Baby" with no further interaction with the crowd.

But Biebs wasn't the only one having a bad night with fans leaving angry that they have forked out hundreds of dollars just to see the star "mime" during his show.

"We paid $337 each for tickets to be close to the stage and it’s an insult that he’s miming through a lot of the songs. It’s obvious when he isn’t as then he can’t even get the words out," a disappointed fan told The SunOnline.

Do you Biebs, do you.
