WALK THIS WAY

Reese Witherspoon and Renée Zellweger bring some star power to Sunday's Walk to Defeat ALS in Los Angeles. It's a cause close to their hearts: Their friend and former publicist, Nanci Ryder, was recently diagnosed with the disease. "She's a tough lady, and she's also determined," Witherspoon said of Ryder's will to fight. "She [told me], 'I am going to raise awareness, and money, and people are going to know what ALS is, and we're going to eradicate this horrible disease.'"
