Katy Perry has officially signalled she is off the market and she did it live on stage.
During her Prague stop on the Lifetimes Tour, the Firework star, 41, reacted to a fan attempting to propose to her for the second time, after a similar moment at her London show.

Holding a marriage-proposal sign and a ring, the fan prompted Perry to set the record straight.
“This guy is trying to get me to marry him and he has a ring in his hand,” she told the crowd, before firmly adding, “No! I am dating someone else, for crying out f*****g loud!”
The singer’s public statement confirmed her romance with former Canadian Prime Minister Justin Trudeau, 53.
Also, this follows weeks of speculation.
The pair first sparked dating rumours in July and appeared openly together in Paris last weekend.
Their relationship was subtly hinted at again on Halloween when Trudeau dressed as a shark — a playful nod to Perry’s iconic Super Bowl performance featuring the viral “Left Shark” dancers.
Sharing a photo with his son, Hadrien, 11, he captioned it: “He’s the surfer, I’m the shark… we built the costume together.”
Katy perry and actor Orlando Bloom announced their split earlier this year.
Also, they share a daughter, Daisy, five.
