Colton Haynes to Exit Teen Wolf?

Colton Haynes will not be returning for Teen Wolf Season 3.

The actor made the surprise announcement himself this afternoon, posting on Twitter:

"These past few yrs have been the best of my life. I'm sad that this chapter has ended, but excited for a new one to begin. Thx for the love."

Haynes' Jackson was revealed to be the Kanima toward the end of Season 2, with the character transforming into a werewolf on the finale.

Teen Wolf creator Jeff Davis has said the series filmed an alternative scene to close that run of episodes, just in case the actor did depart the MTV smash, one in which Jackson dies. Does this mean we now know the creature's fate?

"You'll just have to wait and see," Davis told E! News.

MTV has yet to confirm Haynes' departure, while insiders say contract negotiations fell apart this summer between the two sides. We'll update this story as news breaks.

UPDATE: A MTV spokesperson has told Us Weekly there is "absolutely no truth that Colton is being pushed out or that he, or any cast member, is being replaced. We love Colton and look forward to his returning with the entire cast for Season 3 of Teen Wolf.”
