When it comes to the Kardashians, everything is for sale – including their used lingerie!

Khloé Kardashian, who launched an eBay site with her husband over the summer, recently added some of her personal items to be auctioned off with "a portion of the proceeds" going to Cathy's Kids, Lamar Odom's cancer charity. The items include a used sports bra, yoga pants and a silk bathrobe, and Breaking Celebrity News has the details.

"New year, new wardrobe," Khloé tweeted on Monday with a link to her store, where she had recently listed several of her and her husband's pre-owned items.

On the market for a sports bra? Khloe is selling a pre-owned "Aerie Fit Sports Bra Size S" with a starting bid of $.99.

The reality star listed a pair of pre-owned "Active Basic Black Yoga Pants Size Large" for $2.25, and apparently they are a hot commodity as they received 10 bids in just the first few hours taking them up to $5.50.
