It's fair to say that at Katy Perry concerts, things can get weird.
And her recent residency in Las Vegas - titled 'Play' - is staying true to form.
As well as a singing turd and an enormous facemask, the singer shocked audiences by pouring herself a drink on stage.
The shocking part? She poured the drink out of her bra.
Check out the moment here:In a video of the crazy moment, the 37-year-old pop icon can be seen chatting to a giant facemask on stage.
The star is decked out in a metallic futuristic ensemble, which includes silver boots and appears to be made out of squashed beer cans. Most exciting is the bra part of her dress, which is basically just two giant cans complete with ring pulls.
Sitting down on stage, Perry reaches for a glass tumbler, saying "where's my glass? I need a drink."
With a flick of her long dark hair, the singer then speaks to her audience: "Excuse me one second, I have to go to the bar."
To the crowd's amazement, Perry proceeds to lean over her glass, crack open the can on her left breast, and 'lactate' beer into the cup.
"It's still going!" she cries as the glass begins to fill up.
Eventually, the beer stops. After giving her boob a couple of taps and shakes to make sure it's empty, Perry sits up and goes to take a swig.
The kooky display left many fans confused.
"I think I’m in a fever dream that wasn’t real," one person wrote on Twitter.
"Well…there’s a headline I never thought I would read," commented another.
But for a lot of fans, watching Perry pour beer out of her bra only reminded them why they love the pop star so much - and made them even more determined to go see her in Vegas.
"This is why I love her so much. She's so goofy, weird and hilarious spontaneously and always makes people laugh and smile," one wrote.
"Katy Perry opening a nozzle to pour beer out of her costume is iconic. Queen of camp!" added another.
"Get me to Vegas," agreed a third.
