Today was the 12th Annual EIF Revlon Run/Walk For Women in New York City. The 5K walk, which kicks off in Times Square and ends in Central Park, is an effort to fight women's cancers by raising money and awareness. And even though, the Miley Cyrus/Christina Applegate-hosted Los Angeles walk isn't until next Saturday (May 9th), Hollywood's heavy hitters were out in full force.

Revlon spokeswomen Jessica Alba and Jennifer Connelly, funnyman Jimmy Fallon (not yet a face of Revlon!) and the cosmetics company's newest addition, Jessica Biel -- it was announced yesterday that she is their new "Global Brand Ambassador" -- all hosted the event. (And yes, there were JT sightings.)

Apparently, the Run/Walk event is the perfect place for all the "J"-listers (two Jessicas, Jennifer, Jimmy and Justin).
