Head of record company countersues Kesha

Kesha is being countersued by her record company boss, Dr Luke.

The 41-year-old music producer, who runs Kemosabe Records, claims the 27-year-old 'Tik Tok' singer is a liar and is trying to extort him after she accused him of sexually, physically and emotionally abusing her for 10 years and forcing her to use drugs and alcohol.
