Nicole Richie is an aunt once more! The style icon just became auntie to Cameron Diaz and Benji Madden’s son, Cardinal Madden. The 42-year-old told Access Hollywood at the premiere of “Don’t Tell Mom the Babysitter’s Dead” that she has met the little one and revealed if she was the one who started the family trend of naming their kids after birds. “I don’t know that I started it, but I am down for all,” she said. Nicole also gushed over her new film “Don’t Tell Mom the Babysitter’s Dead.” “I think that anyone who hasn’t seen the original, I’m hoping, will watch this and then watch the original because both are amazing,” she said. “Don’t Tell Mom the Babysitter’s Dead” hits theaters April 12.
