Talk show host Larry King has slammed reports his actress wife Shawn is battling anorexia.

Shawn Southwick King, 48 - who has been married to the 74-year-old TV veteran for 10 years - was admitted to rehab on Tuesday suffering from an addiction to painkillers.

Allegations King suffers from an eating disorder have persisted since photos of her withering frame sparked concerns just prior to undergoing treatment at an undisclosed clinic. But a source tells the New York Daily News, "She's emaciated... She always keeps a smile plastered on her face - but she is really unhappy."

However, a spokesperson for Larry King has denied reports she suffers from depression or anxiety, adding: "She is not anorexic. Nor has she been diagnosed as depressed. She has taken medications because of her migraine headaches that she's had since she was a young girl. She developed a dependency on painkillers as a result of being prescribed medication for the migraines."

The TV actress is King's sixth wife and they have two children together - Chace, nine, and Cannon, eight.
