"The Fourth of July has always been one of my most favorite holidays, ever since I was a little girl,” Leone said. “But when I became an American citizen in June 2006 the holiday took on a whole new meaning to me. I am proud to be an American citizen, and I think celebrating the birthday of our country is a great way to honor our past while looking forward to our future.”
