L’Wren Scott was found dead of apparent suicide on Monday morning in her Manhattan apartment. A spokesperson for the NYPD told Fox411, "A female 49 years of age was found unconscious and unresponsive.”

The New York Post reports Scott, a 6-foot, 4-inch former model, was found by her assistant hanging by a scarf, and it is unclear if she left a note behind. The girlfriend of Mick Jagger was a notable name in the fashion industry, after launching her first collection, “Little Black Dress,” in 2006. Red carpet starlets such as Nicole Kidman, Angelina Jolie and Sarah Jessica Parker have all worn her dresses to the Academy Awards.

Scott has also collaborated with Lancome, Barneys New York, and most recently, Banana Republic, to create an affordable line of clothes, shoes and accessories.

Scott was expected to unveil her autumn/winter 2014 collection during London Fashion Week last month, but was forced to cancel due to production issues. Her boyfriend, Jagger, is currently in Australia with the Rolling Stones, and is expected to perform in Perth.

According to The Daily Mail, a spokesperson for Jagger said the Stones frontman is "completely shocked and devastated."

Scott was born Laura “Luann” Bambrough and adopted by Mormon parents who raised her in Roy, Utah, according to Vogue.
