Pop singer Adam Lambert, who is touring South Africa next month, has reportedly insured his voice for a whopping £30m (R422,356,486.95) ahead of a long run of promotional appearances. According to Sunday Mirror, the singer's management decided to take out a policy to protect his vocal chords last week. A source told the paper: "Insurance for stars is a big deal in the US and Adam's voice is his bacon. He had it insured last week." Adam joins a host of other stars who are rumoured to have insured their body parts. Mariah Carey is said to have taken out a $1bn (£622m) policy to cover her legs, while Dolly Parton has allegedly insured her famous 40DD chest for $600,000 (£373,000). It was recently revealed that the 30-year-old - who finished as runner-up in the eighth season of American Idol - will make a guest appearance in hit show Pretty Little Liars next month.
