I love a fried fish. But I’m also crazy about grilled fish. I love Snickers.” The pop star opened up about the pressures the music industry puts on women to stay thin and said that expectations are changing for the better. “I think it’s changed, thank God,” she had said. “People are more accepting of others. Which is the way it should’ve been from the jump.”
