The reality star said that she wants to drop a few pounds before she ties the knot with fiancé Kris Humphries later this year.
When one of her Twitter followers told her they were 'on [their] way to GNC to by some QuickTrim,' – a weight loss supplement marketed by the Kardashians, Kim, 30, replied, 'Take some for me! I'm about to start again! Wedding slimdown.'
The bride-to-be has previously admitted that she struggled to accept her more voluptuous curves, but thanks to her mum Kris Jenner, she eventually learned to love them.
'Our parents raised us to be comfortable in our own skin,' she said. 'Now I think we like to wear tight things, we love feeling good, taking care of ourselves, wearing what we want.'
