In addition to Michelle Williams, Heath's former girlfriend Naomi Watts is said to be a mess over the death of her ex boyfriend, whom she dated for two years, beginning in 2002. Naomi is currently in Sundance promoting her new film, but has canceled all scheduled press appearances for Wednesday, as she deals with this tragedy.
Naomi's best pal, fellow Aussie Nicole Kidman, said, "What a tragedy. My heart goes out to his family."
Mel Gibson also weighed in: "I had such great hope for him," he said. "He was just taking off and to lose his life at such a young age is a tragic loss. My thoughts and prayers are with him and his family."
Photos of Lindsay Lohan, who was said to be very close with Heath the last few months, were taken yesterday, after she heard the sad news. She was crying and looked very upset in the pics, and because of that, I feel like it's not right to post them. I'm all for making fun when it's harmless, but I think it would be an invasion of privacy to showcase her grief.
