L'Wren Scott, a fashion designer and girlfriend of Rolling Stones frontman Mick Jagger, was found dead in her Manhattan apartment Monday.
Sources say that Scott sent her assistant a text at 8:30 a.m. Monday telling her to come over.
Sources told NY1 that police found Scott hanging by a scarf, but they did not find a suicide note.
Police would only confirm that they responded to a call at an address in Chelsea.
Scott launched her own label in 2006 and has released a number of collections since then.
A spokesperson for Scott confirmed the death in a statement, which read, "At this devastating time for Ms. Scott's family and friends we request that their privacy be respected."
A spokeswoman for Jagger said that the singer was "completely shocked and devastated by the news.''
L'Wren Scott was 49 years old.
