When it comes to family, Ariana Grande takes things seriously. And of course, that goes double when someone picks on her big brother.
One Instagram commenter called her half-brother (and "Big Brother" star) Frankie "that homo," to which Ariana responded:
You said it, sister.
I'm sure Frankie isn't even listening to the haters. He's probably off singing "A Whole New World" at the top of his lungs, not caring at all.
