As for the curiosities surrounding the two singers thirty-third birthdays, Beyonce had Joan Rivers died on her turning of the age. In the case of Brandy, Whitney Houston died on her big day. Just days earlier e! News reported that Whitney Houston had passed a note to Brandy, but to this day, Brandy has not revealed the contents of that note.
While I'm not aware of any movies Joan Rivers and Beyonce starred in together, I am aware of a remake of Cinderella that Brandy and Whiney Houston starred in once upon a time.
