Sir Mick Jagger and L'Wren Scott

Sir Mick Jagger is "completely shocked" by the death of L'Wren Scott.

The Rolling Stones singer was on tour with the band in Australia when he was informed his partner of 13 years has died of an apparent suicide today (17.03.14).

His spokesperson said: "He is completely shocked and devastated by the news."

Fashion designer L'Wren was found hanging from a scarf on a doorknob in her home in Manhattan, New York, by her assistant at around 10 o'clock this morning.

The assistant went to the apartment and let herself in after receiving instructions to do so by text message from L'Wren.

A New York police department spokesperson said: "At approximately 10.05 hours police responded to 200 11th avenue.

"Upon arrival, officers discovered a 49-year-old female, unconscious and unresponsive. Emergency Medical Services also responded and pronounced the aided DOA [Dead On Arrival] at the scene. The investigation is ongoing and the medical examiner will determine the cause of death."

New York Police have also said there is no suspicion of foul play connected to the death, but they are awaiting the examiner's formal report.

L'Wren - a former model, who stands at 6' 3" - had met Mick on a photo shoot in 2001 when she was working as a stylist. They started dating, but didn't appear together publicly until 2005, when they attended the Golden Globes ceremony. In recent years they had divided their time between New York and London - where she has a design studio - and also owned a flat in Paris together.

After years as a successful model and stylist, L'Wren launched her own brand in 2006, which became a favourite of many celebrities, including Sarah Jessica Parker, Michelle Obama and Christina Hendricks.

Her friend, actress Nicole Kidman, said of her clothing: "She knows what aspects to accentuate in a woman, and is able to make you feel incredibly sexy and sophisticated when you are in one of her exquisite designs."

L'Wren was born Luann Bambrough in Utah and raised by adoptive parents before moving to Paris while still a teenager to work as a model.

Her fashion career also included designing costumes for films, including 1996's 'Diabolique', 'Ocean's Thirteen', 'Eyes Wide Shut' and 'Shine a Light', a documentary about The Rolling Stones.
