Watch : Ariana Grande’s Brother Frankie Defends Her From Big Brother CastmateFrankie Grande’s ego is small—but he’s still Grande. In a livestream from the show, Kamu yelled into the ether, “Frankie Grande, tell your sister to hit me up!” “Not a f--king chance Kamu,” Frankie wrote in an Aug. 6 tweet alongside a selfie of him at Ariana’s Eternal Sunshine tour. For dedicated fans of Big Brother, Kamu and Frankie’s latest back and forth is just the tip of the iceberg where their beef is concerned. The Titaníque star previously called for Big Brother to remove Kamu, as well as fellow contestant Rick Devens from the latest season for anti-drag comments they made during the stream last month.
