Conan O'Brien Breaks News Of Robin Williams' Death To His Audience, Gives Emotional Tribute

Conan O'Brien was in the middle of taping Monday night's "Conan" when he heard about the news of Robin Williams' unexpected death.

After an interview with Will Arnett, O'Brien addressed his audience and broke the news.

"We tape these shows a few hours early, and by the time you see this now on TV, I'm sure that you'll know. I'm sorry to anybody in our studio audience that I'm breaking this news - this is absolutely shocking and horrifying, and so upsetting on every level," the red-eyed host explained.

Arnett, who worked with Williams on the 2006 movie "RV," told the crowd what a wonderful man the late actor was:

"As funny as he was-he's truly one of the all-time greats-he was even better as a person. He was even more fantastic-just the loveliest, sweetest, one of the kindest guys that I've ever worked with. Just such a soft, warm, emotionally sweet guy, and it's a major, major loss for everybody."

An emotional O'Brien continued:

"We're just processing this information literally right at this moment, and so we are thinking of Robin's family. We're thinking about everybody who he touched around the world, throughout his life. We're thinking about Robin tonight. There's really not much else to say ... God bless Robin Williams."
