Katy Perry is an award-winning singer-songwriter, but her nonagenarian grandmother helps keep her grounded. “My grandmother is in charge of my morals,” Perry once said. “I do anything wrong, she’ll come after me.” Perry is so close to her grandmother, Ann Hudson, that she often brings her as her date to awards shows and premieres. Hudson has accompanied Perry to the Grammy Awards (pictured), where she sported a bedazzled cane that Perry got her, the Billboard Music Awards, and even to meet President Obama. More recently at the Smurfs 2 premiere, Hudson walked the red carpet with Perry, wearing a shirt that said “I’ve got the hots for Papa Smurf.” It’s no wonder Perry loves her spunky grandma.
