The 15 year old, recently cast as a werewolf in Eclipse - the third film in the franchise, sparked a frenzy among fans after announcing Summit Entertainment movie executives had two more sequels in the pipeline, bringing the number of installments in the saga to five.
Twilight author Stephenie Meyer has only written four novels in the hit series the films are based on.
Stewart told Access Hollywood, "I heard that there were going to be three more movies. There's going to be Eclipse, Breaking Dawn, and there should be one more.
But the new recruit has backtracked on his previous remark, telling RadarOnline.com, "There was some false communication, so far it's just Eclipse that's coming out.".
