Nicole Richie held two bottles of fresh juice as she ran errands in LA yesterday. She's back home after a relaxing vacation to Mexico over the holiday weekend. Nicole attended the wedding of publicist Meredith O'Sullivan in Cabo San Lucas along with some friends, including Jessica Biel. Nicole's now gearing up for an eventful month. She launched her first fragrance last week, and her second QVC clothing line debuts this Thursday. Nicole's capsule collection for Macy's Impulse hits stores on Sept. 12, and she'll celebrate her 31st birthday later this month.
