NEW YORK (CBSNewYork/AP) -- Mick Jagger took to Facebook Tuesday to speak out about the death of his longtime girlfriend, designer and celebrity stylist L'Wren Scott.
Meanwhile, as CBS 2's Alice Gainer reported, there was word Tuesday that the company owned by Scott was heavily in debt.
For the past decade, Scott, 49, walked the red carpet as the longtime girlfriend of the Rolling Stones front man while also designing the clothes for his tours and dressing celebrities such as Penelope Cruz, Amy Adams and Nicole Kidman.

Monday morning, Scott was found dead in her Chelsea apartment after an apparent suicide; no note was found and there was no sign of foul play, police said.
"I am still struggling to understand how my lover and best friend could end her life in this tragic way," Jagger wrote on Facebook. "We spent many wonderful years together and had made a great life for ourselves. She had a great presence and her talent was much admired, not least by me. I have been touched by the tributes that people have paid to her, and also the personal messages of support I have received. I will never forget her."
An autopsy was conducted Tuesday. Results were not immediately available.
The designer had texted her assistant 90 minutes earlier and asked her to come to her apartment but didn't say why. She was found kneeling with a scarf wrapped around her neck that had been tied to the handle of a French door, police said.
"L'Wren was so generous and warm and smart and tough, which is why I think a lot of people are very shocked about what happened," said Samantha Conti of Women's Wear Daily.
Conti attended several of Scott's fashion shows over the years, but just last month Scott abruptly cancelled her London Fashion Week appearance.
"Officially, she canceled it because there was a delay with the delivery of fabrics, there wasn't going to be enough time to get extra special pieces together," Conti said. "There are reports that she was in debt."
The company owned by Scott was heavily in debt at the time it filed its most recent accounts.
Accounts filed by LS Fashion Ltd. in London show the company had liabilities that exceeded assets by $5.9 million as of Dec. 31, 2012.
The company's long and short-term debts totaled 6.75 million euros against assets, capital and reserves of 2.51 million euros, according to the accounts, which were filed in October.
Among the stars who wore Scott's designs was actress Olivia Wilde.
"L'Wren Scott was brilliant, elegant, kind, and generous,'' Wilde wrote on Twitter. "What a tragedy.''
The Rolling Stones have called off tour dates in Australia and New Zealand following Scott's death.
The band said in a statement Tuesday they "are deeply sorry and disappointed to announce the postponement of the rest of their 14 ON FIRE tour'' and thanked fans "for their support at this difficult time.''
The Stones were scheduled to play Wednesday in Perth, Australia, and at other stops this week and next week, including Melbourne and Sydney.
