The last people who knew about "Big Brother" houseguest Frankie Grande's secret was his fellow houseguests. But to many who had been following the CBS reality television show's 16th season, Grande actually has a famous sibling. And you could probably guess from the last name who she is.

According to her IMDb profile, Ariana Grande-Butera gained recognition as Cat Valentine in "Victorius," and later on played the same character alongside Jennette McCurdy in a short-lived sitcom called "Sam & Cat." She is more famous as Ariana the singer, whose single "Problem" with Iggy Azalea had propelled her as a promising superstar.

Her brother Frankie, who was nominated for eviction from the house last week, revealed this bit of information first to the guys except housemate Donny, said Cinemablend. Caleb admitted in the episode that he had never heard of his sister. Derrick, who is a cop in real life, started asking more questions about Frankie's revelation and also talked about how people conceal their lives outside the house to fellow housemates.

But perhaps the most memorable reaction from the house came from Victoria, who has admitted on the show that she is an Ariana Grande fan. She seemed very excited with the revelation. 

Frankie earlier admitted that he has been hesitant of telling people who he really is outside of the house, considering the history of people in the show who get booted out because of their fame. The openly gay housemate, who is also a YouTube personality, told People magazine, "I don't want people knowing that I have a social media following and that Ariana Grande is my sister because I feel like both of those things will put an unnecessary target on my back. They will assume that if there is an America's vote or America's player that I will win it because I have a viral following. So if I am recognized as soon as I get into the house, I have to win and I have to do damage control."

Meanwhile, Ariana supported her brother's decision to reveal things about himself in an August 9 tweet. She said, "Frankie might've just saved his game tonight!!! werrk @FrankieJGrande! told his whole truth & apologized for playing dirty like a man. proud."

Bustle agrees, considering that Ariana has 17 million followers to count on to. The site wrote, "Let's be honest. Ariana Grande's campaigning really helped Frankie get voted onto the Team America alliance. The house guests also worried that Frankie was the reason there was no America's Favorite this season because he would win it by default. Essentially, Frankie's identity gives him an unfair advantage over everyone else in the game so it might be in their best interest to cut him loose."
