But the 16-yer-old Hannah Montana star is apparently diverse when it comes to keeping herself in shape. Cyrus (born Destiny Hope Cyrus) hit up a Pilates class in Toluca Lake, California, yesterday, accompanied by her older half-sister, Brandi. (Born in 1987, Brandi was adopted as a young child by Miley's dad, Billy Ray Cyrus.)

Hey, when a girl's preparing to promote her big-screen epic,  she needs to do everything she can to keep herself looking and feeling good.

And it's always nice to have a sibling to endure the workout with. The family that sweats together, stays together, right?
