Nicole Richie and Jessica Alba Lounge by the Pool During a St. Barts Trip

Jessica Alba and Nicole Richie took to relaxing poolside today in St. Barts. Jessica chatted with Nicole on lounge chairs after stepping aside earlier in the day to check her phone and making her way through a crowd with her husband Cash Warren. The two friends have been trading off fedora duties over their past two days on vacation together.

Jessica and Nicole are currently in the tony vacation spot as part of a 10-year anniversary celebration for their friends, movie producer Jamie Patricof and model Kelly Sawyer. Jessica wore a bikini on Wednesday as she splashed around the ocean with her Cash, but opted to cover up her two-piece with a short tunic while hanging out with Nicole and a group of pals. However, Cash was still enjoying his ocean playtime as he went snorkeling near the beach while Jessica took photos.
