Plus, we had also forgotten that in between tweeting and doing Pilates, Miley is also a pretty good actress and we couldn't be more excited to welcome her back to our screens.
In the film Miley plays a teenager who works as a private investigator sent on a secret mission to go undercover at a school.
You can watch the trailer here.
Think Never Been Kissed meets Mean Girls.
Plus, Kelly Osbourne makes a cameo appearance which got us pretty excited.
In other Miley news, the star got all dressed up for Halloween last night, choosing to dress up as Nicki Minaj.
We reckon this might just be our fave celeb fancy dress yet!
We wonder if she padded out her bum?!
However we're not sure what actual Nicki Minaj will make of Miley's choice, is it a compliment or an insult when people start dressing up as you for Halloween.
