Kim Kardashian And Friend Show Off Their Best Assets In Workout Selfie [PICS]

It's no doubt that Kim Kardashian is back (no pun intended). She is back to her old ways, as far as showing off that one thing that made her famous... Her boooooty! It's back and baby got back. Kim loves showing us her post-baby booty. The 33-year-old owes most of her weight loss to the Atkins diet, and pure hard work-outs. So what do you think, is Kim K's booty back?

After looking at this pic, I would say ... YES! This was taken after hitting the gym with her new friend Blac China aka Tyga's girlfriend. You cant deny that Kim is looking great.
