Last week was bittersweet for Beyonce Knowles. The 31-year-old and her husband, Shawn "Jay-Z" Carter experienced their first legal setback since they gave birth to their daughter, Blue Ivy. On the day that it was announced that Beyonce will headline the half-time show during the 2013 NFL Superbowl, the singer lost a legal battle against a Boston wedding planning company over exclusive rights to the name Blue Ivy.
