Hollywood's famous siblings almost bares it all in their new ad for their lingerie line "Intimates"

Kardashian sisters, Kim, Khloe and Kourtney, donned a series of sexy lingerie to promote their Kardashian Kollection Intimates line.

Kim shared in her website, "My sisters are I are excited to reveal our new ad for our Kardashian Kollection Intimates! The intimates line is so gorgeous, comfortable and feminine and we are very proud of the line!"

The picture was taken a long time ago before Kourtney got pregnant as no baby bump is showing. Lingerie is the newest addition to the reality trio's already growing brand that consists of denim, handbags, shoes, jewelry and women's apparel in the Kardashian Kollection.

Immediately after the release of the ad, Kim later tweeted a picture of herself reclining sexily on a bed wearing just a pair of tiny pink silk shorts, holding a sheet to her chest to protect her modesty.

The 31-year-old reality star cheekily accompanied the shot with the caption: 'Can't sleep tonight ...'

It is believed the shot was taken from an upcoming campaign for Kardashian Kollection Intimates. All of the Kardashian Kollection goods is exclusively available at Sears.
