Robin Williams' longtime friend Lance Armstrong quickly reacted to the news of his death with a heartfelt message to the man who publicly stood by him through his doping scandal.
Lance tweeted, "RIP Robin. I will always remember you as one hell of a friend. I love you and will miss you terribly."
Williams remained a staunch supporter of Lance through all the accusations of him using performance enhancers -- frequently standing by his side at fundraisers for Armstrong's Livestrong Foundation.

Like most of Lance's friends, Robin had his limits though. After Lance finally copped to cheating ... Robin backed away, at least publicly, and turned down invitations to attend some Livestrong events.
