VIDEO : Lady Gaga's Family Didn't Know She Was Raped Until Oscars Performance

(CNN)While Lady Gaga went public in 2014 with her story of being raped, apparently, not everyone in her family heard it. The singer has revealed that her grandmother and aunt didn't know she was a survivor until her powerful Oscars performance Sunday night. "My grandmother (in the middle) and my Aunt Sheri (on the right) both called me the day after the Oscars because I never told them I was a survivor," Gaga wrote in the caption of a family photo she posted on Instagram on Tuesday.
