The death of fashion designer L'Wren Scott is being ruled a suicide.

  The confirmation came down this afternoon from the New York Medical Examiner's Office. 

The 49-year-old former model was found dead in her Manhattan apartment Monday. 

Her longtime boyfriend, Rolling Stones frontman Mick Jagger, is said to be devastated over her death. 

Jagger and his band have cancelled a string of concert dates in Australia and New Zealand in light of the tragedy.
