Comedian Conan O’Brien was informed of the shocking death of comedic actor Robin Williams during a taping of his TBS show, “Conan," Monday afternoon, taking a moment at the end of the program to express his sorrow at the Hollywood legend’s passing.

“This is.... upsetting, but we got some news during the show that Robin Williams has passed away,” O’Brien revealed to the sound of audience gasps. “I’m sorry to anyone in our studio audience that I’m breaking this news. This is absolutely shocking and horrifying and so upsetting on every level.”

O’Brien’s guest at the time, actor Will Arnett, who worked with Williams in the 2006 comedy film “RV,” also took a moment to remember the 63-year-old Oscar-winning performer, who'd battled addiction and depression for many years.

“As funny as he was, and he’s truly one of the all-time greats, he was even better as a person,” Arnett said. “He was just one of the loveliest, sweetest, one of the kindest guys that I have ever worked with. Such a soft, warm, emotionally sweet guy, and it's a major, major loss for everybody.”

“We are just processing this information right at this moment,” said O’Brien. “We are thinking [about] Robin’s family. We’re thinking about everybody who he touched around the world throughout his life. We’re thinking about Robin tonight … God bless Robin Williams.”

On Monday, a rep for Williams confirmed that the star of memorable films such as “Good Will Hunting,” “Mrs. Doubtfire” and Disney's “Aladdin,” had been found dead in his Northern California home from an apparent suicide.

“Robin Williams passed away this morning. He has been battling severe depression as of late,” William’s rep said in a statement. “This is a tragic and sudden loss. The family respectfully asks for their privacy as they grieve during this very difficult time.”
