Britney Spears

Britney Spears celebrated Cinco de Mayo with friends and family -- including fiance Jason Trawick -- at a house party in Brentwood, California, on Saturday. The 30-year-old singer sported a red belly-baring top and casual denim cutoffs for the festive occasion, which commemorates the Mexican army's 1862 victory over France at the Battle of Puebla during the Franco-Mexican War. In U.S. cities with large Mexican populations (such as Los Angeles), it also serves as a celebration of Mexican heritage and pride. (5/5/2012)
