 Aerosmith and dream on. Richard Simmons passed away on Saturday, which was the day after his 76th birthday. His rep said he celebrated it the day before, and there's no word on the cause of death. Richard's brother Lenny said, quote, I don't want people to be sad about my brother. I want them to remember him for the genuine joy and love that he brought to people's lives. Keep in mind, he did say in a social media post back in March that he was dying, but then he said, no, no, no, not like literally.
