Kim Kardashian appears in the new TV ads for Carl's Jr. Premium Salads, but she confirms she wasn't paid to post on Twitter about the healthy fast food meal.

"I want to clear this up because there has been a lot of talk about this. Carl's Jr did not pay me to tweet about their salads," Kardashian, 28, wrote Thursday on her blog.

"Yes, obviously I was paid to be in the commercial... we all have to work! But I was not paid to tweet or talk about the salads on my blog, Facebook account, MySpace account or any other online outlets," she adds.

"I want my fans to know what products, gadgets, foods, clothes and beauty products I like and I love sharing all that with my fans. You all know I've posted about certain clothes and products on my blog since I started blogging two years ago."

The reality TV beauty often tweets about QuickTrim and she's a paid endorser of the weight loss cleanse.

Past Carl's Jr. spokeswomen include Paris Hilton, Audrina Patridge and Padma Lakshmi.
