Photos: Miley Cyrus celebrates 22nd birthday today with boo, Patrick Schwarzenegger & some wild things

Wild child Miley Cyrus celebrated her 22nd birthday in true Miley style.

The pop star celebrated with new boyfriend Patrick Schwarzenegger, 21, and several friends at a West Hollywood nightclub, where she was presented with an enormous pizza cake and rode a mechanical ride in the form of a penis.

Miley, who had used giant inflatable phalluses on stage during her Bangerz tour concerts, arrived at her party in a colorful outfit, consisting of a bright pink top that connected with a ring to her fluorescent green mini skirt, covered with a pink and yellow fur jacket. She sported blue eye shadow, blue and yellow hearts painted on her face and pink and blue butterfly clips in her short hair.

She was photographed near the Factory Club with Patrick (dressed in an olive green flight suit), her brother Braison Cyrus, 20 (dressed in plaid), and friends. Singer and actress Sky Ferreria also attended the party.
