Conan O’Brien paid emotional tribute to Robin Williams after learning of the comedian’s death during Monday’s taping of his TBS late night show. 

The audience, seemingly unaware of Williams’ death, can be heard gasping in shock after the late night host reported the tragic news.

O’Brien admitted to being “stunned” to learn Williams had passed away as he shared memories of the comedy giant with “Conan” sidekick Andy Richter and guest Will Arnett.
