Yes, the actual Jon Snow off Channel 4, not Kit Harington. Not that that makes it any less weird. 

The gaffe came while Jon was interviewing Richard Wilson from One Foot In The Grave. The reporter asked Wilson if he knew that his friend Rickman was terminally ill with cancer, and - when Wilson replied "I did", Jon responded: "so it wasn't a case of 'I don't believe it' then." Seriously. He went there. 

Obviously there was a backlash to the comment...

Leading Snow to release the following by way of an apology: "I apologise unreservedly it was a mistake in the heat of a sad moment." 

If you are going to throw in a quip while reporting on someone's death, at least make it original.
