She's already been transformed into an alien for her new video E.T.
But it looks like Katy Perry may be seeking inspiration from this world as well, as she becomes a female gladiator.
In a new promotional shot from her forthcoming new video, which premieres on Thursday, the singer wear a gold breastplate and dramatic make-up, inspired by the ancient Roman look.

The new single, which is already in the top of the U.S. Billboard charts, sees Miss Perry team up with rapper Kanye West.
Over the last week, Perry has been leaking sneak peeks of the video shoot before the promo is seen in its entirety on Thursday.
Perry's other worldliness appearance is inspired by the lyrics of the song, about falling in love with a foreigner.
The song contains many extraterrestrial references, hence Perry's sci-fi appearance in another image.
Perry is currently on the UK and Ireland leg of her California Dream World Tour.
On Monday, she was embroiled in a Twitter row after Scottish DJ Calvin Harris pulled out supporting her Dublin gig.
Calvin was scheduled to open for Katy’s gigs but cancelled at the last minute after being angered over set arrangements.
The furious I Kissed A Girl singer vented on Twitter, posting: ‘Calvin Harris will NOT be joining in on the fun and has CANCELLED last minute.’

To which Calvin, 27, replied: ‘Sorry to all who wanted to see me with Katy – her team suddenly moved the goalposts and I was to appear on stage with no production.’
Katy hit back again with: ‘The goalpost seems to be perfectly fine for New Young Pony Club, Yelle, Robyn, Marina & The Diamonds, to name a few.
‘Or how bout Janell Monae and her 16 piece band… It’s fine, I’m used to you cancelling on me, it’s become ur staple!’
Calvin then tried to explain by tweeting: ‘It would have looked s***, sounded s*** - trust me you would have been more disappointed SEEING the show than u are with me cancelling.’
He then began complimenting Perry, tweeting: ‘Her show is AWESOME, you’ll have an amazing time without me. (especially w/o me DJing on a cardboard box in front of a pink curtain)
Absence makes the heart grow fonder: Her husband Russell Brand was spotted at Los Angeles' LAX airport yesterday
And then apologised, posting: ‘I’m really sorry @katyperry I’m just upset because I really wanted to play but ur team made it impossible.
‘We tried really hard to sort it out, but playing side of stage for 30 mins, it seemed pointless me even being there. Didn’t intend to cause offence or upset anybody.’
Perry is yet to accept his apology on Twitter.
Meanwhile, her husband Russell Brand has enthused about the couple's long-distance romance.
The comedian, who was spotted flying out of Los Aneles yesterday, told The Sun: 'Considering her schedule and the way I'm working as well, it's amazing.
'She does two or three gigs then has four days off. During those days we're meeting. She's been brilliant. We're still excited to see each other.'
