Halle Berry teamed up with Modern Family star Julie Bowen to kick off the 20th annual EIF Revlon Run/Walk For Women in LA today. The event raises money for research, treatment, and support of medically underserved women with cancer. She has been a supporter of the beauty brand and its various charities since 1996, when she first signed on as a beauty ambassador. Halle dropped by the charity walk while on a break from filming her upcoming movie, X-Men: Days of Future Past, alongside Hugh Jackman and Jennifer Lawrence. Aside from working, Halle has been keeping active during her second pregnancy and was even spotted wearing gym clothes yesterday leading up to the Revlon event. She isn't the only star who is supporting Revlon's race — Emma Stone and Olivia Wilde hosted the Revlon Run/Walk in NYC last weekend.
