Lorre was at the heart of the Sheen scandal - and the target for the actor's most barbed attacks.
But at the end of the most recent episode of his show - now with Ashton Kutcher as the star - Lorre revealed in a message on vanity-cards that he was not done with the feud.
Insisted that 'something inside me died' during the war of words, he insisted that it was eating away at him and forcing him to act.
Although he said that he wants to move on now that a lawsuit with Sheen has been settled, he wrote 'There's just one problem.
'That thing inside me that died? It walks at night. It's angry. It's hungry. And worst of all... it's writing a tell-all book.'
In the vanity card, Lorre also likened being sucked into the Sheen scandal to becoming 'the unwilling contestant in a reality show... pretty much hated every second of it.'
