Watch Britney and Iggy Flip Hair and Lip Sync 'Pretty Girls'

New fake best friends Britney Spears and Iggy Azalea teamed up for a bubbly performance of “Pretty Girls” at the Billboard Music Awards.

Beaucoup lip syncing here, so feel free to watch it on mute and enjoy Brit’s choreo and Iggy’s futile dancing. Still trying to figure out Britney’s outfit. And I think we can all agree that Iggy Ig looks… different.
