Better not piss off little sister Ariana Grande by insulting her big brother Frankie! The 21-year-old pop singer launched a tirade this week on Instagram against a fan who posted a gay slur about her half-brother.

Ariana Grande posted a photo of her and brother Frankie on Instagram after he revealed she was his sister to the Big Brother 2014 cast. One visitor to her Instagram feed made a snarky comment on the photo calling Frankie “that homo.”

After seeing the nasty comment, Ariana laid into the commenter full force with language that might even make her bro Frankie Grande blush!

“that ‘homo’ is the fiercest, most incredible, funniest, most intelligent, kind hearted and most LOVED person on the face of the planet. he also cleaned up his game and told the truth to everybody in the house WHICH by the way nobody else on that show has done. so I don’t give a flying fuck if or when he comes home!!! he is incredible and I am SO proud!!!! ….. oh and also…. “that homo” gets more ass than you’ll ever get in your live. k miss thing?”

We’re betting when Frankie Grande gets out of the Big Brother 16 house, he is going to feel really awesome about how vehemently his little sis defended him. We should all be so lucky to have that kind of family behind us.
