Ke$ha raised the wacky factor at the American Music Awards on Sunday. The singer who has TiK ToK’ed her way into every awards show this year hit the red carpet in a custom made VHS tape gown, which featured a plunging neckline and a high slit. Talk about vintage!

Nicki Minaj also stood out like a sore thumb, wearing a brightly hued and ornately embellished Manish Arora dress, while Miley Cyrus enjoyed walking down her last red carpet before her 18th birthday, looking gorgeous in Marchesa.
