Miley Cyrus Winsor Pilates black gym outfit Miley Cyrus Winsor Pilates black gym outfit

Miley Cyrus went to Pilates yesterday in Beverly Hills, and not only does her body look AMAZING in this little black Free People dress, but it seems like the workout put her in a great mood!

Between her five mile runs and regularly going to Pilates, the 19-year-old starlet has been looking better than ever lately, but she doesn't have any movies or TV shows in the works, so it appears as though she's just doing it just for herself ... and boyfriend Liam Hemsworth! Of course, we are getting into bikini season now, so maybe she wants to win best celebrity beach bod? She's already got our vote!
