Miley Cyrus recently glammed up the 13 Annual LA County Walk to Defeat ALS with her surprise appearance.
The 22-year-old songstress popped up on stage to support Mari Winsor, a celebrity Pilates instructor, reports E! Online.
After her workout, the ‘Wrecking Ball’ hit-maker said that she is already sweating and added Winsor made her do a happy workout and has kicked her ass once again.
