Lady Gaga attended her 18-year-oldsister’s (Natali Germanotta) graduation ceremony at New York City’s Convent of the Sacred Heart wearing an outfit only Gaga would deem appropriate. She probably just wanted to shock the heck out of the nuns, for the fun of it. LOL. Hmm, this is actually close to “normal” for Gaga attire, right? My question is, how does she walk in those shoes?!
