Noah posted a TikTok video of himself with his head on white pillows and a grey hoodie on.
On the video, the actor said he spent 18 years trying to hide his sexuality from those who knew.
The post received an overwhelming response in the comments section and on Twitter.
Twitter users said he took care of Will in "Stranger Things" and called him a "icon."
A third fan joked that Noah would release a silly recording in 2023.
A fifth person posted about how happy he was that a celebrity from a minority group was coming out to the public.
Netflix has hinted at Will's sexuality throughout the seasons. Season 4 episode 8 is an example.
Will consoled a friend who was upset about his girlfriend.
Will was "100% gay" and in love with his best friend, but he hadn't told his best friend yet.
