Sen. Kirsten Gillibrand, Rep. Carolyn Maloney, and a galaxy of Broadway, Hollywood and television stars crowded the main stage in Central Park early this morning to help kick off the GMHC’s 27th Annual AIDS Walk New York. Stars on hand included Wendy Williams, Grammy nominee Keri Hilson, NCIS: Los Angeles star Barrett Foa, Tony winner David Hyde Pierce, Glee’s Dot Jones, designer Jason Wu, and Ugly Betty’s Michael Urie, who played to the squealing fans in the front row by throwing HIS underwear in the face of good sport Nick Jonas.You can find all of that and much more in the slideshow below, plus lots of shots of the more than 45,000 walkers who jammed Central Park from end-to-end today. To date, AIDS Walk New York has raised more than $122 million for programs and services in the tri-state region. My personal thanks to GMHC Communications Director Dirk McCall for looking after me all morning. Full-screen photos are here.
