Khloe Kardashian has lost 20lbs in just 20 days.

The 'Keeping Up With The Kardashians' star began to pile on the pounds when negative public speculation about on her marriage to Lamar Odom increased.

The 27-year-old businesswoman apparently took refuge in comfort food after her 32-year-old husband, was thought to blame her for the embarrassment of being put on the Dallas Mavericks' inactive list.

However after intense training with her basketball player partner, she has dropped a dress size, according to Life and Style Weekly.

Khloe, is the tallest of her famous sisters at 5ft 10in to her sibling Kim's 5ft 2in frame.

She has posed in an indigo bikini in a new issue of the publication under the heading: 'How I got thin fast!'.

Her quick weight loss has been credited to eating healthy meals cooked by a personal chef and hardcore exercise classes with a personal trainer.

Eldest sister Kourtney posed on the same magazine's cover in July last year to declare she has lost 33lbs in pregnancy weight after giving birth to son Mason in December 2009.
