Kate Gosselin left her own kids at home but shook hands and took pictures with hundreds of others at the Stars, Stripes and Skates event benefiting the Heritage Foundation of 9/11, an organization that promotes patriotism and volunteerism in the wake of September 11.
Professional ice skaters Johnny Weir, Oksana Baiul and several others put on a spectacular show. In addition to Kate, The Real Housewife of New York City star Jill Zarin and Hairspray's Nikki Blonsky made presentations about the Foundation's mission.
Kate's appearance came just hours after her estranged husband Jon Gosselin did his own charity thing.
Jon was the star attraction at an autism event in Philadelphia.
Kate has been making an increasing number of appearances outside of her TLC reality series Jon & Kate Plus 8.
Kate also guest-hosted a week of ABC's The View.
