10 years ago today, Gaga tweeted about the Applause music video and her upcoming appearance on Good Morning America. "MY 1ST MUSIC VIDEO IN 2 YRS PREMIERES IN LESS THAN 26 HRS on @GMA AND VEVO! #APPLAUSEVID819 A fashion, pop, performance art fantasia!" "I WILL BE LIVE at Good Morning America to greet fans at 44th & Broadway tune in at 8am EST on @GMA to watch my first tv interview for ARTPOP" "So who is coming to @GMA to watch my music video on the jumbo screens in times square!? I can't wait to see you in NY, my hometown kids!" Later in the day, a fan tweeted Gaga telling her that they spotted Perez Hilton in her family's apartment building, in an attempt to stalk Gaga. Gaga, after being silent with the Perez feud for a long time, finally spoke out against Perez refusing to be quiet about the issue this time. "@PrinceNeptune_ i need to know if this is true" "@PrinceNeptune_ this is EXTREMELY EXTREMELY serious and if it is true i have to know" "@BrookeB15 if he is still there please take a photograph…even from outside the window is fine. this is extremely serious" "@PrinceNeptune_ is he still there now? i need you to take a photograph please this is very very serious. and not a funny joke if it is one" "@BrookeB15 @PrinceNeptune_ i'm asking the doormen to let you in so you can see if he's still there" "@PrinceNeptune_ what time did this happen" "@PrinceNeptune_ ok security is on the way over, and it will be handled. thank you for telling me, don't be scared." "@perezhilton STAY AWAY FROM ME + MY FAMILY YOU ARE SICK TRYING TO RENT AN APARTMENT IN MY BUILDING TO STALK ME. LEAVE ME ALONE!!!" "@PrinceNeptune_ I have confirmation from the building he was there. Thank you so much for telling me. I will handle it." "DO I NEED TO BE SHOT IT IN THE HEAD FOR PEOPLE TO UNDERSTAND THAT HIM AND EVERYONE ELSE THAT HARASSES ME HAS GONE TOO FAR? IM A HUMAN BEING" "I just want to make music+make people smile. Im sorry to all the fans who are trying to enjoy whats suppose to be a happy time. Gone too far" "@PEREZHILTON YOU ARE A LIAR I KEPT EVERY PSYCHOTIC TEXT U SENT TO MY PHONE. I NEVER RESPONDED+NOW YOU'VE STALKED MY HOME. BOY WHO CRIED WOLF" "I will NOT handle this privately, the internet is just the surface of what the public sees. I've been quiet for a long time, not this time." Gaga was seen leaving Chateau Marmont Hotel on her way to the airport to leave Los Angeles and fly to New York City.
