Kim Kardashian has allegedly been sleeping in a corset to try and lose weight.

The 'Keeping Up With The Kardashians' star has been preparing for her upcoming nuptials to Kanye West, which are reportedly set to take place at a secret Paris location next month, by trying out a number of natural beauty treatments and weight-loss methods while on holiday in Thailand with her family.

A source told Grazia magazine: ''Kim wants he figure to look absolutely perfect on her wedding day. Wearing a corset at night is extremely uncomfortable but has a proven record of results, and with six weeks to go, Kim is up for anything.''

The brunette beauty - who gave birth to her and Kanye's first child, North, last summer - also underwent the ancient procedure of ''butt, face and breast slapping'' which reportedly costs £200 for a 15-minute session and erases wrinkles, shrinks pores and tightens skin.

The source added: ''Kim did a lot of reading into these natural techniques online before her trip, and she had three 15-minute treatments of each while she was there.''
