Pop worlds collided Saturday night in Atlantic City, when news broke that Lady Gaga was in attendance of Britney Spears’ Femme Fatale tour. Britney Spears stopped the show before her song “I Wanna Go” and gave Gaga a shout out saying she was honored to have her at the show. Gaga responded by making a heart symbol with her hands and waving. Gaga stayed the entire duration of the show — dancing with her friends, and leaving just before the encore. Check out video of the event below!
