The 'Wrecking Ball' singer had a birthday bash in West Hollywood, where she was presented with a giant pizza cake and rode a mechanical ride, reported People magazine.
In a photo, Cyrus was seen outside the club with her brother Braison Cyrus and Patrick following her behind.
Cyrus donned a neon pink and lime green cut-out dress paired with a pink and yellow fur jacket.
The 'See You Again' hitmaker completed her look with light blue eye shadow, blue and yellow hearts painted on her face and colourful butterfly clips in her short hair. Patrick, meanwhile, dressed up in a green pilot jumpsuit.
