Socialite Kim Kardashian reportedly sleeps in a corset to lose weight.

Kim will soon marry rapper-fiance Kanye West and she is said to be sleeping in a corset to look perfect, reports femalefirst.co.uk.

"Kim wants her 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," said a source.
