Kourtney and Kim Kardashian know how to command attention when it comes to plugging their upcoming reality show Kourtney and Kim Take Miami.

The two sexy sisters are glamming it up ... posing side by side while striking fierce poses in this new promotional photo.

By the looks of this shot by photographer Brian Bowen Smith, seems as though Kourt has lost all of her baby weight! Then again, perhaps the photoshop fairy came to spread holiday cheer.

Kourtney and Kim Take Miami premieres January 20. We can't wait!
