Big Brother 16's contestant and Ariana Grande's brother, Frankie Grande, offends the family of another contestant for a rape joke that he made. Now the family wants Frankie's parents and Ariana Grande to publicly apologize for the tasteless joke.

TMZ reports that the family of "Big Brother 16" houseguest Victoria Rafaeli is now very displeased over a joke that Frankie made about her. Frankie jokingly said that two guys should team up to take Victoria's virgnity, and no matter the intention, the family cannot let it go. They think the joke is considered a rape joke and that rape jokes are never funny. They now want Frankie's family, including his famous sister, Ariana Grande to apologize.

Adding to the ire of Victoria's family is that Frankie did not just say told two of his housemates to team up and take away Victoria's "virgnities," he also made some sexual gestures to go with the joke. The family took this as very offensive and bothering.

Victoria's mother, Lizbeth shares to Twitter that she thinks Frankie's comments should be construed as a "rape joke." Moreover, the worried mom now thinks Victoria could be a "target for rape" because the producers did not put a lid on Frankie's rant.

Victoria's mom now wants Frankie to directly apologize to her daughter. In addition, she also wants to see Frankie's parents and sister Ariana to apologize in public.

The distraught mom tells TMZ, "I want Frankie to imagine people saying this stuff about his sister and see if he thinks it's funny."

Ariana Grande has yet to react, but she is said to be really close to his brother Frankie, while Frankie is her number one fan. Despite being busy promoting her album, "My Everything," Ariana Grande has been watching the "Big Brother" episodes regularly and talking about it because she misses her brother so much.

While wishing his brother can win, she also wants him back home as soon as possible. "It's been amazing to watch him, but it's been frustrating. It's been -- ugh -- annoying. I miss him so much. Like, I miss my best friend. I love him so much. But I'm so proud of him, because this is something he's wanted to do for a very long time," shared Ariana Grande once to Billboard.com.
