The reality star has regained her gorgeous figure

Kim Kardashian has revealed her killer post-pregnancy body by stripping down to a skimpy bikini in Miami.

The reality star, 33, looks stunning in snaps of her strolling along a beach in the white two-piece, which displays her impressively flat stomach and toned derrière.

Kim is wearing natural-looking make-up in the photos and her blonde locks fall loosely over her shoulders, while her huge diamond engagement ring from Kanye West is clear to see.

She’d been joined by pal Jonathan Cheban and a dark-haired beauty on her day out.

Kim was mocked for her weight gain while pregnant but is believed to have lost over 56lb through exercise and the Atkins diet since giving birth to daughter North in June.

Despite her incredible weight loss, the mum-of-one said on US television last week that she thought her body was just ‘okay’ in the images and that she ‘still has about 10lb to go’.

But it seems Kim was feeling a little more confident while fully-dressed last night.

She uploaded an Instagram snap of herself with two pals at 36-year-old Kanye‘s concert in Chicago wearing a very sheer black dress that put almost her entire chest on show.

‘My Chi girls @larsapippen @kristennoelgipson,’ Kim captioned the hot shot.
