In the episode, Frankie reads an emotional letter from his mother breaking the sad news out loud to the house cameras.

"Although it is difficult, we thought it was the right thing to tell you," he reads. "We love you so much and want you to know that grandpa said specifically a few days ago, that if anything were to ever happen, he wanted you to know how proud he is of you and that he is rooting for you to win."

Later, Frankie breaks down in tears, but is more determined than ever to win his season of the popular reality show.

"But I'm gonna be strong, and I'm gonna stay, and I’m gonna win HOH and I'm gonna win this game,” he says. "I'm gonna do it for my grandfather."

Ariana also took to Twitter Wednesday to express her sadness, and to thank fans for their support.
