After her revealing night at the CFDA Awards, Lady Gaga was ready to party. The Icon Award winner and close pals headed to the Top of the Standard at New York’s Standard Hotel for a star-studded V magazine fete that drew out revelers like Gerard Butler, Kirsten Dunst and more. Guests sipped Belvedere cocktails named after Gaga songs, and enjoyed a surprise performance by Patti LaBelle, who serenaded the crowd with “Over the Rainbow” as Gaga joined in at the end of the tune.
