Reese Witherspoon traveled to Rio de Janeiro to promote This Means War last week. She stepped out in a bright yellow Louis Vuitton dress for her first appearance in front of the cameras on Thursday, and was back in the spotlight in a floral Erdem look on Friday. Once Reese wrapped up her second press event, she changed into a black sundress and bikini and headed to the pool at her hotel. Reese had a copy of Catching Fire, which is the second book in the Hunger Games series, in her hand as she settled in to soak up the sun. The actress was back in LA by Saturday night, with plenty of time to spare until the big-screen debut of The Hunger Games movie on March 23. While Reese was away this weekend, her husband Jim Toth met up with pal Justin Bartha for lunch at Gjelina in Venice, CA.
