LeAnn Rimes guest starred on Thursday night's episode of Anger Management as a suspected psychopath that both seduces and scares Charlie Sheen's character.

The country singer played a woman named Winona on the FX comedy series who goes on a date with Charlie Sheen's therapist character. Charlie picks up her up at a prison, at first unaware that she is related to one of his most violent patients there. Winona has a bother who is a serial killer on death row and Charlie is left questioning whether or not it runs in the family when the two go out on a date. When they get steamy in a convertible during their date, Rimes wears a tight-fitting pink dress. At one point she straddles Charlie, making a move on him.

Charlie is turned on but unsure of what to think of Winona. The contents of her car's trunk also concerns him: he by accident finds an axe, bleach, duct tape and begins to believe he is on a date with a serial killer.

The two characters are next seen together in the bedroom after having just made love. For the scene, Rimes wore a laced orange slip dress and heads out to get them both some beers from the kitchen. Impressed with her moves in bed, Charlie asked, "where did you learn all that?" to which she replied with a naughty smile, "In France." Rimes then scared Sheen's character by showing him a collection of roadkill skulls in her bedroom.

Rimes closed the show in a short jean shirt and lace top that showed off her cleavage. Her character keeps Charlie guessing whether or not she is a serial killer like her brother.

After the episode aired, Rimes tweeted, "Thx sweet peeps for the love @AngerMgmtFX it was great fun."

Anger Management airs Thursdays on FX at 9:30 p.m. ET.
