Kim Kardashian "trains" waist in corset

Kim Kardashian has apparently revealed she is “waist training” by lacing herself into a tight corset.

The US reality star has previously said she was struggling to lose the last bit of baby weight after welcoming daughter North in June 2013.

And it seems she has found the solution as she posted a selfie on Instagram which showed her waist cinched into a black and purple corset.
