Angelin Germanotta - the 25-year-old singer`s grandma on her father`s side - has revealed she always listens to her granddaughter`s music and doesn`t mind the sexy outfits because she cannot see them. The 80 year old told Life & Style: "I listen to her songs. I love her music! "I`m blind, so I really don`t see all those sexy outfits. I can only see her legs when she is on TV, so it`s good that she wears those outfits, so I can spot her." Despite being known for her outrageous clothes - including a dress made of meat and nothing but a piece of see-through plastic and some strategically-placed sticky tape - Angelin reveals Lady Gaga was not always so rock and roll. She added: "She wears jeans and just ordinary clothes with the family. She was a straight-A student, did all of her homework and went to Mass!" Her grandmother`s openness may have inspired Lady Gaga`s father Joe to lead an unusual life, with the `Judas` hitmaker previously confessing she has inherited her wild streak from her dad. She said: "He was having sex with girls under the boardwalk in New Jersey before he went to see Bruce Springsteen. "He saw a lot of himself in me. My first piano teacher was a stripper. My dad told me later. I used to say to her, `Why do you have such long nails?` She just said, `Someday you`ll understand why.` "
