Love disapproved of the idea and went public with her feelings, insisting the thought of the movie vampire playing her late husband was "stupid" and "wrong".
Her comments appear to have upset the Brit, who has attacked her in a new article, in which he insists he's tired of reports linking him to a Cobain portrayal.
Pattinson tells Britain's The Mirror newspaper, "You see all these comments, like from Courtney Love, saying 'What the f**k! He's totally wrong for it,' and I'm like, 'I f**king said no, you d**k!' I didn't get offered it. For one thing, I'm too tall, and I can't sing like him, I'm nothing like him!
"I love Nirvana, but I love them a bit too much. I'd be embarrassed (to play Cobain)."
