"I will miss her friendship deeply,” Johansson said. “She touched all of those that knew her with a warmth, intelligence, thoughtfulness, beauty and grace."

"Annabel was one of those people that just made life better," said Andrew Safir, founder of film marketing firm The Cinema Society. "Every party, every dinner, every gathering was better when she was in the mix. Funny, gorgeous, stylish (obviously), and so much fun, with a knowing and charming and sometimes naughty twinkle in her eyes. Every fashion party and glittery gathering will now be missing her special spark."
