Beyoncé and Jay-Z hit up Nobu for a date night in NYC yesterday. Earlier in the evening, Beyoncé attended a Michelle Obama fundraiser along with other celebrity supporters, including Robert De Niro, Whoopi Goldberg, and both Beyoncé and Jay-Z's mothers. Beyoncé and Jay-Z left their daughter Blue Ivy at home, but the proud new mom is still paying homage to her little one with her hot Victoria Beckham collection dress and nail polish colors. Last week, Jay-Z headed to Austin to perform at SXSW and now Beyoncé is gearing up for her postbaby return to the stage as well. She is set to headline three shows over Memorial Day weekend and B is also reportedly working on a deal to go on tour later this year.
