Conan O'Brien ended his show Monday night with a heartfelt and emotional tribute to the late Robin Williams after learning of the actor's death during the taping of his show.
The late-night host broke the news to his audience, which elicited a shocked gasp from most of those watching, and it was clear the news had hit Conan, his co-host Andy Richter and guest Will Arnett pretty hard.

Williams had been a guest on Conan's show several times, and Arnett had worked with Williams in the 2006 comedy RV.
"This is absolutely shocking, and horrifying, and so upsetting on every level," a distraught Conan said.
"He was an amazingly kind and generous person," added Richter. "It's got to be a terrible time for his family and our thoughts go out to them."

"As funny as he was – he's truly one of the all-time greats – he was even better as a person," said Arnett. "He was even more fantastic. He was just the loveliest, sweetest and one of the kindest guys that I've ever worked with. Such a soft, warm emotionally sweet guy. And it's a major, major loss for everybody."
Conan signed off on the emotional moment saying, "Goodnight, and God bless Robin Williams."
Williams passed away on Monday, Aug. 11. He was 63.
