A man has been arrested and charged after storming the stage at a Katy Perry concert.
The American singer, 40, was perfroming at Qudos Bank Arena in Sydney as part of her The Lifetimes World Tour on Monday when the incident occured.
Footage circulated online captured the moment that Johnson Wen – known online as Pyjama Man – crashed her rendition of 2008 hit, Hot N Cold.
Wen could be seen running up to her and grabbing her shoulder, while excitedly jumping up and down, before he was then escorted off stage.
For her part Perry - who is engaged to 48-year-old British actor Orlando Bloom - looked furious.

She then told the confused crowd: “Well, there’s never going to be another show like this, so just enjoy it, Sydney.”
Adding: “What the hell is going on?”
According to 9News, he was arrested after the incident, and taken to Auburn Police Station.
Wen was eventually charged with entering enclosed lands, as well as obstructing a person in the performance of their work or duty.
After being granted conditional bail, he was issued with a six-month ban from entering the Sydney Olympic Park Precinct, and is due to appear at Burwood Local Court on June 23.
Speaking to the Australian news outlet afterwards, Wen claimed his stage invasion had been for fun and went on to recall how Perry had “freaked out” when she saw him.

“I said, ‘Let me get on stage with you”, then she freaked out because she realised I wasn’t a performer,’ he explained.
“I was about to do like extra Fortnite moves but security got there too quick.”
This isn’t the first time that Wen has done something like this.
He was previously banned from the Olympic Park for crashing the Weeknd’s concert, and also invaded arenas at the Olympics, the Women’s World Cup and the Cricket World Cup final.
Wen has now vowed to mend his ways, adding: ”I’m planning to quit forever because you get in way too much trouble for it. Especially me, because I’ve done it so many times.”
