Reality star Kim Kardashian likes to share her latest news with her fans and her most recent update is the secret to her small waist.

Posting this pic to her Instagram page, the 33-year-old Keeping Up With The Kardashians star and designer (Kardashian Kollection) owner showed how this bright purple corset helps keep her looking trim. 

She wrote: "#hourglass #waisttraining #nophotoshopnecessary". 

The 33-year-old has made no secret of the fact that she is working on slimming down. She tweeted last week: "Off to an intense workout. Can't seem to shake this last 15-20 lbs of baby weight. No more excuses. My baby is 1 years old! UGH."
