As much as fans adore him and many are beyond keen, others are annoyed that someone who has made some past mistakes is still getting work.
Old tweets of Colton have resurfaced, here he took place in "black face" controversy three times.
It is also next to a photo of Lena Dunham, who is also joining the cast. In the same tweet, it shows when she was slammed online for abusing her little sister.
"The AHS Cult cast ," the caption reads, obviously being sarcastic, and showing disappointment in show creator Ryan Murphy's decisions.
Colton apologised for his actions, but we guess it doesn't necessarily mean that everyone has forgiven him.
As for Lena, Twitter went crazy when they heard she was cast, even going as far as #cancelling the show.
Lena has also apologised for her mistakes in the past, but we guess not everyone is welcoming them with open arms onto their fave TV show...
