Forget the girl who started as a country singer then landed a role on Hannah Montanna....as Miley Cyrus has shown a more rock bad-ass side to her!
Miley was celebrating her manager Adam Leber's 40th birthday along with other A-list celebrities including Aussies Sia and Liam Hemsworth.
Celebrations seemed to be pretty loose and wild so why wouldn't Miley taking the stage to sing Nirvana's Smells Like Teen Spirit....
In true Miley style her performance was loud crazy but managed to get everyone in the crowd up and dancing!
It is a very different sound to what we are used to hearing from Miley but we love that shes back doing what she loves best.
It’s fair to say Miley’s manager won’t be forgetting his 40th birthday anytime soon!
