Miley Cyrus Rode A Mechanical Penis For Her Birthday

You were expecting a bouncy castle?

Miley Cyrus rode a giant mechanical penis during her birthday party Saturday in Los Angeles.

In a relatively NSFW photo she posted to her Instagram, the 22-year-old "Wrecking Ball" singer is seen with pal Katy Weaver on the gizmo -- a raunchy twist on the mechanical bull.

As E! notes, Cyrus has used giant inflatable phalluses on her Bangerz tour.

Cyrus's new beau Patrick Schwarzenegger attended the party, but there's no word on whether he took a spin on the device.

Some outlets had fun with their headlines: "No Bull! Miley Cyrus rides mechanical penis," the New York Post headline blared.
