Kim Kardashian Tweets Topless Photo In Bed (PHOTO)

Insomnia struck reality TV queen Kim Kardashian last night and things got a little racy.

The 31-year-old entrepreneur shared her sleepless night with her nearly 14 million Twitter followers, writing: "Can't sleep tonight ..."

Perhaps Kim can't sleep because she's too excited over the revealing photo she posted. We wouldn't be able to sleep either if we were wearing a full face of makeup while posing half-naked, covered only by a bedsheet.

Kim gave no explanation for the sexy photo, but the post does coincide with the launch of her Kardashian Kollection lingerie line.
