Kim Kardashian Loves to Sleep Naked

Kim Kardashian likes to sleep naked.

The reality TV star -- who is currently dating American football player Reggie Bush -- prefers going commando in the sack because it saves on washing -- and she gets a better night's sleep, too.

She says, "I love to sleep naked. I don't do it all the time, but I do sometimes.

"It is so much more comfortable. And it saves on washing too, which is great."

Kardashian, 27, recently denied reports her curvy figure is down to plastic surgery.

In a blog post -- accompanied by a a bikini-clad photo of herself at age 14 -- Kim wrote, "I hope after seeing this you guys will never ask me a plastic surgery question again.

"I have had a size C since I was 11 years old!

"All the butt implant rumors are just so not true and now just silly to me."
