Nicole Richie was in her bikini again yesterday to hang out on her balcony in Cabo San Lucas. She went south of the border for a weekend to attend the wedding of publicist Meredith O'Sullivan at Las Ventanas al Paraiso. Jessica Biel was among the guests. While Nicole hung out with a group of friends at the resort and out on a golf cart yesterday, Jessica went shopping and caught a flight out of town. The last week has been jam-packed with travel for Jessica, who also fit in a visit to the Puerto Rico set of her fiancé Justin Timberlake's Runner, Runner.
