Nicole Richie stood out in yellow while Justin Timberlake wore a sharp suit for Saturday night's Environmental Media Awards in LA. Justin took the stage to accept the EMA Futures Award for his continued focus and commitment to environmental activism. It was a weekend full of parties and social responsibility for Nicole and her husband Joel Madden. Joel partied with his brother, Benji, and friends Jessica Alba and Cash Warren at Friday night's star-studded Decade of Difference Gala. At Saturday's solo event Nicole wowed in a flirty, yellow Keepsake dress, Louboutin heels, and a House of Harlow clutch. Yesterday, Justin was back to work and focused on his acting career. He sat down with us at the In Time junket and said when the film hits theaters on Oct. 28 you'll see plenty of his running skills. In sad news, Justin's racing team suffered a horrific loss last night when William Rast driver Dan Wheldon was killed in a 15-car accident that occurred during the Indy 300 in Las Vegas.
