Neither one of them strangers to the strangest of headlines, Michael Jackson and Britney Spears also shared a stage.
The duo performed "The Way You Make Me Feel" together for Jackson's 30th Anniversary Celebration, which aired on CBS in 2001.
"I was so excited to see his show in London," Spears said in a statement today. "We were going to be on tour in Europe at the same time and I was going to fly in to see him. He has been an inspiration throughout my entire life and I'm devastated he's gone!"
Justin Timberlake posted a tribute to Jackson on his website.
"I can't find the words right now to express how deeply saddened I am by Michael's passing," the pop-R&B hitmaker wrote. "We have lost a genius and a true ambassador of not only Pop music but of all music. 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."
And the proof of Jackson's tremendous influence on the next generation of music makers didn't stop there.
