Gaga`s father struggled to accept changes

London: Pop star Lady Gaga admits her father struggled to accept her wacky on-stage persona, as he was not happy to see his daughter performing in her "bizarre outfits".

Gaga reveals her father, Joseph Germanotta, was not impressed when he first saw her stripping off onstage. "He was not happy with me being in my underwear... But you know what, I think that deep down he knew I always had it. I just think it`s hard to watch your kids grow up and change and become themselves. I think also, my dad was a bad boy and he loved rock `n` roll, and I think the thing that terrified him the most was he saw himself inside of me," dailystar.co.uk quoted her as saying. IANS
