And the Broadway community is a tight-knit family.”

“He’s a great guy. Ethan’s a wonderful guy,” the Big Brother alum continued, saying how Ariana’s happiness is so important to him.

“He’s very sweet. He’s very very very sweet. I just, I adore him,” Frankie continued about Ethan, ​32. “I, honestly, I’ve always just said this, all I want is for my sister to be happy and when she’s happy I’m happy. So I’m very happy.”

“I feel like we don’t need to go into any specifics, but, of course, there’s like an insatiable frustration, inexplicable, hellish feeling with watching people, misunderstand the people you love and you and anything,” Ariana said during the interview.
