L'Wren Scott, a fashion model and designer who has dated Mick Jagger since 2001, was reportedly found dead in an apartment in Chelsea this morning. A source familiar with the investigation says that Scott's body was found by her assistant at around 10 a.m. in a unit at 200 Eleventh Avenue.

The Post and the Daily News are reporting that Scott, 47, was found hanging by a scarf from a doorknob. An NYPD spokesman said they could not confirm the identity of the victim because the family has not been notified. The spokesman added that the Medical Examiner will determine the cause of death. Jagger's Twitter account posted this photo of the Rolling Stones singer in Australia earlier today.

According to the Post, "Scott had sent the unidentified assistant a text message about 8:30 a.m. saying, 'Come by,' police sources said." Last month, Scott had cancelled her London Fashion Week show, citing production delays and said the collection would be shown via social media. However, a Post source said, "L’Wren’s business just crashed."

Scott, born Luann Bambrough, was adopted by a Mormon couple and raised in Utah. After photographer Bruce Weber spotted her 6'3" frame (with 42" legs), she modeled for Chanel and Thierry Mugler in Paris. In the 1990s, she moved to LA and became a stylist for Vanity Fair and Rolling Stone, eventually designing her own clothes for shoots.

In 2006, Scott started her own fashion label, emphasizing sexy, form-flattering clothes; she told the Telegraph, "I've never met a woman who thinks she's got a good enough figure." Her designs have been worn by Nicole Kidman, Penelope Cruz, Kate Moss, Sarah Jessica Parker, Madonna, Michelle Obama and Christina Hendricks. (Hendricks wore a Scott design at the Vanity Fair Oscars party last month.) Last fall, Scott worked with Banana Republic on a collaboration, that was by all accounts a success.
