Ariana Grande’s Grandfather Dies

Tragedy for Ariana Grande and "Big Brother" contestant Frankie Grande. Their beloved grandfather has died.

TMZ reports CBS plans to keep the news from Frankie while he's in the "Big Brother" house.

It seems just before he died the grandfather knew Frankie might bail from the show if he found out, so one of grandpa's last wishes was to keep his death a secret from Frankie.

Ariana was chronicling her grandpa's illness, recently posting pictures with him in the hospital.

Ariana made her grandfather's wishes clear, tweeting:

It seems from the "Big Brother" live feeds that Frankie is still in the dark over his grandpa's death.
