Kirsten Dunst famously had her purse stolen from her suite at the Soho Grand in 2007, and she’s now giving up another one through Page Six Magazine, inside today’s Post, for charity. Dunst’s navy Sofia Coppola for Louis Vuitton handbag includes all her favorite things — a total worth $5,264 — and can be bid on at nypost.com/kirstenauction. Proceeds will benefit Art of Elysium, which helps sick children at New York hospitals. Dunst says the charity is “a part of my family.” Her bag, stuffed full of designer beauty products, a Bulgari ring and an Isabel Marant wallet, is “elegant and simple — I use mine every day.”
