Katy Perry has joked she wore black to the premiere of her new concert movie Katy Perry: Prismatic World Tour, because she is in mourning for the end of the live shows.

The Dark Horse singer was joined on the pink carpet by her pet pooch Butters, who has been her mascot on the tour, which began in Northern Ireland in May last year, and is still going, with more Asian and South American shows taking place in April and May.

Katy told E! News: “I’m in mourning because this tour is almost finished.”

The 30-year-old singer said she is very proud of the movie and the tour.

She revealed: “I was in the editing bay for quite a long time in different spots around the world because I wanted to make sure I wasn’t nervous and proud of the presentation of this tour, because this tour has been kicking my butt all over the world for almost a year.”

But while she’s been feeling the physical strain of the live shows, she hasn’t suffered any injuries.

Katy said: “I’ve never gotten hurt. I would say I barely fell once but it’s very hard to find on the internet and it just never made the news… Thankfully everything has been really protected and we pray right before for that protection. And we are really well rehearsed.”
