Justin Timberlake says Michael Jackson was a "genius" and "and a true ambassador of not only pop music but of all music."
The pop sensation, who has said Jackson influenced him, wrote on his Web site, "He has been an inspiration to multiple generations, and I will always cherish the moments I shared with him on stage and all of the things I learned about music from him and the time we spent together. My heart goes out to his family and loved ones."
Fellow *N SYNC member JC Chasez also released a statement, saying, "Words can't begin to describe my sadness for the loss of Michael Jackson. I was honored and humbled to have the opportunity to perform with him several times and he had a profound influence on my career. Michael forever changed the world of music and entertainment and I will always remember him for his kind and sweet spirit."
