Reese Witherspoon [1], Courteney Cox [2], Jennifer Garner [3], and Renée Zellweger [4] showed their philanthropic sides when they stepped out together at the 14th annual LA County Walk to Defeat ALS [5] on Sunday. Courteney brought along a sign that read "Team Nanci Love," while all the ladies posed for photos wearing their "Team Nanci" t-shirts in honor of Nanci Ryder, the veteran Hollywood publicist who was diagnosed with the disease two years ago. Reese also shared a cute group photo from the charity event [6] on her Instagram, writing, "Walking today to support #ALS research, with our friend Nanci Ryder who has done so much for all of us. We ❤️you Nanci! For all of you out there as well who would like to help support, a link to donate is in my bio. Every little bit counts to help #FindACure! 🙌 #TeamNanci."
