VIDEO : Miley Cyrus and Liam Hemsworth Dress Up in Gold for a Birthday Theme Party

Miley Cyrus and Liam Hemsworth are a golden couple...literally! The dynamic duo attended a birthday party for Samantha Hemsworth , Luke Hemsworth 's wife, which seemed to have a gold theme. Wayne Coyne , lead singer of The Flaming Lips and Miley's tour partner, also attended the glittery soiree. Miley, Wayne and Liam really went all out for Samantha's birthday party, opting to wear sparkly gold spandex, shorts and jerseys. Although it was Samantha's celebrate, it might have been Luke who won the day, with his head-to-toe golden cowboy ensemble that even featured a holster and gun.
