Sienna Miller joined her GI Joe castmates Friday for a screening of their film at Andrews Air Force Base in Camp Springs, MD. Channing Tatum took a break from his perfect married life to pass out gifts to the troops, while Sienna posed for photos with Rachel Nichol. The promotional tour rolled on to NYC over the weekend, giving Sienna some time to go casual in harem pants before her many outfit changes today. She showed off three looks while making the press rounds, continuing on in her worldwide fashion show.
