Despite this sad news, Ariana's brother Frankie, who is a current contestant on "Big Brother," is not expected to be pulled off the show -- this according to one of their grandfather's last wishes.

"Asked grandps last week if he wanted us to pull Frankie off bb & he said, 'No way! He's gotta play the game even though I don't understand it,'" Ariana tweeted on Wednesday.
