Britney Spears spent New Year's Eve (31Dec08) in New Orleans, Louisiana at a family wedding.
Big brother Bryan exchanged vows with little sister Jamie Lynn's manager Graciella Sanchez, and then rang in 2009 as a married man.
A source says, "Only close family and a few friends attended."
Spears and her brother celebrated the nuptials on New Year's Day (01Jan09) with a shopping trip to a local Wal-Mart superstore.
