The party took place at Beacher’s Madhouse on Sunday, after Miley's kitty performance at the AMA Awards.
To set the scene, the theater was wallpapered with photos of Miley and decorated with blow-up dolls, hundreds of balloons, and giant cutouts of the tongue-wagging birthday girl.
Famous faces (who had to sign confidentiality agreements) included Kelly Osbourne, Emma Roberts, Liam Payne and Niall Horan of One Direction, Wiz Khalifa, Amber Rose, Cherie Daly and Tyler the Creator. There was even a Lorax sighting!
The birthday girl received a $150K Swarovski-encrusted, gold-dipped bottle of Beau Joie champagne and a larger-than-life cake topped with a nearly naked Miley Barbie doll. A mini-Miley got into the groove of “Blurred Lines," recreating Cyrus' twerktastic VMAs performance with a mini-Robin Thicke!
Wild child Miley Cyrus’ 21st birthday party went down just as you would expect… with twerking, naked Barbies, One Direction and more!
