Selma Blair, who? LeAnn Rimes brought sexy back to Anger Management!

The country crooner made a racy guest appearance on the FX sitcom Thursday night, simultaneously titillating and terrifying Charlie Sheen. She may not earn an Emmy for the guest spot, but LeAnn does turn heads as a suspected psychopath whose brother is a serial killer on death row. Her character Winona frightens Charlie's therapist character (also named Charlie) to the core once he discovers compromising contents, including an axe, in the trunk of her car as well as skeletons in her closet (literally!).

Then again, she straddles Charlie and teaches him a thing or two in the bedroom so he's not too turned off.

LeAnn sizzles on screen in several cleavage-baring outfits, including a hot pink bandage dress and lace tangerine negligee. "Big hair, minimal wardrobe!" she tweeted about her look. Minimal, indeed!
