So fierce: Britney Spears and Iggy Azalea took to the stage at the Billboard Music Awards in Las Vegas on Sunday to perform their new single Pretty Girls
Covering the majority of her shapely pins were PVC thigh-high boots for a saucy dominatrix feel.
Iggy wore a metallic mini skirt with halterneck crop top and showed off pink dip-dye ends in her blonde tresses.
Pretty Girls is the first song attached to Britney's highly anticipated ninth studio album.
In anticipation of the performance, Britney tweeted in April a note to her fans: 'Time to put the rumors to bed & take #PrettyGirls to the stage! CAN'T WAIT to perform w/ @IGGYAZALEA at the #BBMAs!'

The duo were seen in early April shooting a music video for the single, which quickly grabbed attention for their retro costumes.
In the video, both Britney and Iggy seem to have gone for a 1980s style with big hair, oversized earrings, and lots of denim.
'She has her verses, I have my verse, but it's not just me kind of popping in it,' the Australian rapper - who co-directed the video - said of Pretty Girls.

While Britney's upcoming album has neither a name nor a release date, the singer has discussed the project numerous times over the past year.
She has meanwhile been busy with a Las Vegas residency at the AXIS and Planet Hollywood Resort & Casino since 2014.
