"I'll give you a clue that the actor playing the character won an Emmy for playing that character, but I won't say who it is," Jean told reporters.
Though The Simpsons is technically a cartoon, unlike other animations, characters who are killed on the show generally stay dead.
The last time a major character was written out of the show was in Season 11, when Maude Flanders was killed off due to the (ultimately temporary) departure of voice actress Maggie Roswell over a pay dispute.
It's also worth noting that many characters have died during the annual "Treehouse of Horrors" episode, but those deaths are considered non-canon.
