Britney Spears took some time to relax in the Bahamas and then made a pit stop in Kentwood, La., for her cousin's wedding. But the pop star - who begins touring again next week - is back to work on a new music video for her song "Radar." "Britney's shooting the video at Bacara Resort & Spa in Santa Barbara," an onlooker tells In Touch. "She has her sons Sean and Jayden with her, too." The star and her crew began filming inside the hotel yesterday, the onlooker adds, saying, "She looks really happy to be there and is enjoying herself!"
