Sex Pistols frontman JOHNNY ROTTEN has launched a scathing attack on the British royal family while filming a documentary about the monarchy.

The 50-year-old punk icon - real name John Lydon - branded the late DIANA, Princess Of Wales a "jealous bitch" and described Prince Charles' wife CAMILLA, Duchess of Cornwall as a "car blanket".

Despite his comments, the GOD SAVE THE QUEEN singer is still hoping to interview key members of the royal family for the as-yet-untitled documentary, which will air on British television later this year (06).
