Lady Gaga celebrated after her sold-out Radio City Music Hall concert with one of fashion’s favorites—Marc Jacobs! The designer accompanied the singer to 1Oak in N.Y.C.’s meatpacking district where bottles of champagne were popped and sprayed, drenching the crowd, including Jacobs! Gaga danced to ’80s tunes and a few of her own hits in a black minidress (heavy on the mini) and shades resembling Mickey Mouse ears. The superstar has reason to let loose—she is nominated for 5 Grammys, including Album of the Year!
