Dylan O’Brien‘s relationship with his brother isn’t as tight as he led some to believe during an interview last week … ’cause his bro says they haven’t spoken in months.

Here’s the deal … the actor recently did an interview with the Gay Times — during which he said he was super grateful for his “trans, nonbinary sibling” before adding he knows other people who are queer and is grateful for how those relationships “deepen my experience in this world.”

Well, Dylan’s brother — who goes by Julz on Instagram and uses he/they pronouns — fired off in the Instagram comments of the Times’ post about the interview … revealing he’s “actually trans masc,” not nonbinary.

Worth noting … DOB is doing press for his new movie “Ponyboi” — the story of an intersex sex worker who is having an affair with Dylan’s character. So, it’s possible Dylan wanted to play up his allyship with his familial tie

It sounds like Dylan may have overplayed his hand here … ’cause his brother is saying the two aren’t that kinda close anymore.
