Fashion designer L'Wren Scott, the girlfriend of Rolling Stones singer Mick Jagger, was found dead in her New York apartment on Monday from an apparent suicide, according to a law enforcement official.

Scott, 47, a former model whose timeless style, modern, classic and sexy fashions were favorites among A-List Hollywood stars such as Nicole Kidman, was found hanging from a scarf in her apartment in the morning.

Police confirmed that a female was found "unconscious and unresponsive" in an apartment building on 11th Avenue in Manhattan.

A spokesperson for Jagger said he is "completely shocked and devastated" by the news. The pair have been dating for several years.

Scott, who was raised in Utah, started her career as a fashion model in Paris before becoming a designer. Last year, she announced a deal to design a small collection for Banana Republic stores.
