The 14-year-old actress told her fans that she identified herself as a queer rather than as a straight or gay on January 15 on Twitter, reports aceshowbiz.com.
The actress posted on social media a screenshot which read: "In my life-only ever liked boys however, I personally don't wanna label myself as straight gay or whatever so I am not gonna give myself labels to stick with - just existing."
Blanchard captioned the image: "Aye!"
Realising that she didn't put comma between the words "straight" and "gay", she tweeted: "Omg I forgot to put a comma between straight and gay pls don't kill me."
She then explained why she identified herself as queer.
"Open to liking any gender in future is why I identify as queer," she wrote.
She was also aware of the consequences of coming out as queer.
She said: "like I thought I was being brave and was proud of myself and then everyone attacks me... Cool."
