Miley Cyrus showed off her dance moves on Wednesday night (12Jun13) when she joined Robin Thicke and Pharrell Williams onstage at a MySpace relaunch party in Los Angeles.

Thicke and Pharrell were performing their chart-topping hit Blurred Lines at the city's El Rey Theatre when Cyrus stepped up to join them, wearing baggy jeans, white stilettos and a top that left her toned stomach exposed.

Thrilled by the chance to 'perform' behind hip-hop mogul Williams, who headlined the bash, Cyrus tweeted: "Big bro (sic) killed it tonight Pharrell."
