The singer dressed up like a femme fatale to attend EPIX's premiere of Katy Perry: The Prismatic World Tour at Ace Hotel in Los Angeles on Thursday night.
Her Balenciaga blazer dress was given an edgy vibe thanks to lace-up knee-high boots that we imagine a dominatrix would love.
Katy also talked about why she's keeping her hair black for a while:
"It's black [because] I'm in mourning because this tour is almost finished."
Awww! That probably explains why her outfit was all black as well!
She's one sexy mourner, that's for sure!
The 30-year-old further revealed that she's looking forward to a beauty break:
"I think it's time for me to have a nap, a little sleeping beauty for a second."
A dark berry lip completed the devilishly hot look!
