Ariana Grande's brother, Frankie, a contestant on "Big Brother", received the devastating news of the death of their grandfather on the show Wednesday.

Viewers watching the CBS live feed online witnessed Frankie reading a letter from his family which broke the heartbreaking news.

His sister Ariana was also able to watch as Frankie received the news, later tweeting, "Watching @frankiejgrande talk abt grandps after reading our letter on the live feed. sobbing/laughing u frankie so much."

Ordinarily, "Big Brother" contestants are denied Internet, phones or outside communication, and there was much speculation as to whether or not Frankie would find out about his grandfather's passing.

Ariana and Frankie's grandfather died Tuesday night after battling cancer.
