The event was the first time the 30-year-old singer has stepped out since giving birth to her daughter Blue Ivy Carter. It only took one month for Beyonce to get back into her Louboutins. The singer wore sparkly Christian Louboutins, an Alexander McQueen gold clutch and Ofira & Lorraine Schwartz gold jewelry.

After Jay-Z's concert Beyonce accompanied him to the 40/40 Club, where the power couple hosted an afterparty, according to the New York Daily News.
