She is wearing a red, ruched, over-the-knee Alice By Temperley dress and Christian Louboutin heels. This is Beyonce's first public appearance since she and Jay-Z welcomed their first child, daughter Blue Ivy, on Jan. 7, 2012. During Jay-Z's performance, he sang several of his hits as well as his new song, 'Glory,' which he penned about his new baby. ( Photo / Kevin Mazur/WireImage)
