Katy Perry plunges her face into ice cold water before her Canada shows

Katy Perry revealed her unusual pre-show ritual as she prepares to take her Lifetimes Tour to Canada. The singer, 40, shared a quirky video to Instagram showing herself plunging her face into ice cold water as part of her pre-show routine. In the clip, she dipped her face into a bowl of iced water while breathing into a blue tube and timed how long she could hold her face in freezing cold water. Katy pulled her reddened face out of the icy water after 18 seconds before going back in for another eight seconds, then declaring that she was 'done'. 'It hurts my brain, I'm done,' she shared. 'I tried to look better for you Canada, I don't care.' Katy revealed that it was all part of a beauty ritual, though some of her team appeared less than convinced as one could be heard saying it was 'so stupid'.
