"Big Brother" producers just broke the news to Ariana Grande's brother that his grandfather passed away -- and the whole 'BB' house is rallying around him.
TMZ broke the story earlier today ... Frankie Grande's grandpa died on Tuesday, but Ariana obeyed his final wish -- to keep his death secret from Frankie, and allow him to continue on 'BB.'
But this evening producers passed a note to Frankie from his family ... which revealed the sad news.
According to bloggers watching the 'BB' live feed -- Frankie broke down in tears and shared the news with everyone else in the house. Some of the other house guests are crying too.

It's extremely rare for "Big Brother" producers to break quarantine and allow contestants to get news from the outside world. One of the only times we can remember it happening is for 9/11.
Still unclear at this point who made the final call in this case. We're reaching out to producers.
