We reveal the star's secret pre-wedding weapon

Kim Kardashian’s resorted to a bizarre ice cube diet to ensure she’ll look like a million dollars at her wedding.

The 8st 10lb TV star, 30, who was snapped hitting the gym last week, is determined to drop to 8st or less before tying the knot with basketball player Kris Humphries, 26.

Kim swears by ice cubes with hoodia plant extracts, which curb your appetite,’ a source tells Now.

And it’s working – she’s lost 3lb.’

The ice cube supplements boost energy – and, thanks to the active ingredient P57, also help signal to your brain when you’re full so that you won’t overeat.

Kim heard about the ice cubes from a friend,’ says our source.

She’s eating them before meals and nibbling on them instead of calorific snacks.’

While hoodia ice cubes are currently only available in the US, you can get the same results using Perfect Hoodia capsules (£16.95 for a month’s supply, hoodia-shop.co.uk).

Dissolve the powder from the capsules in water and freeze to make your own cubes or swallow the capsules whole to avoid the hoodia’s bitter taste.
