Charles and Camilla release statement regarding the death of Tara Palmer-Tomkinson

A close friend of the royal family, she had attended the wedding of Charles' son Prince William and his wife Kate in 2011.

As a London "It Girl" in her 20s, Palmer-Tomkinson became notorious for her hard-partying ways and a not-so-secret cocaine addiction, according to the BBC.
