Kim Kardashian wants to sex you up — and salad you up.

The 29-year-old Keeping Up with the Kardashians star is featured in a new commercial for Carl's Jr. that starts airing this week.

"I'm such a neat freak. Everything's got to be clean, crisp and tasty. And while the best things in life are messy, it's fun to get clean," she says in the commercial, eating in bed in some curve-hugging lingerie then — with, uh, dressing on the side — immersing herself in a bubble bath.

An announcer intones: "Who said salads can't be hot?"

It debuted on E! News Monday night. Footage from the spot also aired on the cable channel's Daily 10.

But now the California-based chain, which has outlets mostly in the Western U.S., is offering a new cranberry, apple, walnut grilled chicken salad.

Kardashian has been dieting and tweeting about the spot.
