Katy Perry has left fans furious after marking her birthday in a very unusual way.
The singer is currently on her Lifetimes tour and celebrated her birthday on October 25 while on the road.
To mark her 41st birthday she stepped out in public for the first time with her new beau, former Canadian prime minister Justin Trudeau (which was on no one's bingo card for 2025).

Sporting a long red dress, Perry and Trudeau were spotted leaving a cabaret show at the Crazy Horse Paris hand-in-hand.
As well as enjoying a night on the town in Paris, Perry was gifted a large birthday cake by her tour crew.
In a video shared on social media the 'Firework' hitmaker is seen blowing out her birthday candles in front of everyone — but it's what she did next that raised eyebrows.

In true Steve Aoki style, Perry then picks up the cake and flings it a member of the crew, who ducks out the way just in time.
Some of her dancers then take bits off the cake to try from the floor. The video seems to show Trudeau looking on as all this happened.
People have since been sharing their thoughts online. Somebody penned: "Katy Perry’s team surprised her with a birthday cake and she straight up threw the whole thing at someone, wasting it all… this woman is actually pathetic."
Another person fumed: "A grown 41-year-old woman not caring about the person who will clean up her mess & the person who put hard work into making that cake. She needs to touch grass."
"Like, someone took the time to make that cake with love and she just throws it on the floor," noted another.
But not everyone believes that what the singer did was so bad. Somebody said in Perry's defense: "There are actual things you can be mad at Katy Perry about but wasting a birthday cake should not be one of them. Please get a grip."

"As a baker, if I got paid then it’s theirs to do what they want with it," said someone else of people's sympathy for the cake maker.

A third added: "I’ve never seen someone get so much heat for throwing a cake at someone else. This is so weird."
"It’s not that deep," insisted a different person on Twitter.
