Lady Gagahas blasted critics who compare her to Madonna in a series of tweets. The singer, who will release her new albumARTPOPnext month, posted the messages to her over 40 millionTwitterfollowers on Sunday (October 20), addressing not only the Madonna controversy but also reports of her alleged drug abuse and rumors that she is an "hermaphrodite". Addressing comparisons between her 'Born This Way' aesthetic and a picture of Madonna wearing a high ponytail in the '90s, Gaga tweeted: "LADY GAGA IS A REDUCTIVE MADONNA COPY! SHE'S OVER NOW! #WriteWhatUWant #SayWhatUWantBoutMe #ImNotSorry."
Gaga also posted a 2012 interview with Cynthia McFadden in which Madonna described her work as "reductive", adding: "I don't need anybody's permission to be remembered. I will be. Whether they like it or not."
Finally, she addressed her recent chart feud with Katy Perry, citing criticisms for her single 'Applause' not debuting at number one like Perry's 'Roar'.
The singer wrote: "... #UWontUseMyMind I write for the music not the charts."
Katy Perry has been criticized by a feminist author for her latest music video.
The singer's visual for new single 'Part of Me' sees her joining the US Marines after discovering that her partner had cheated on her.
However, Naomi Wolf - who admitted that she used to be a fan of Perry - has criticized the star for the pro-military message included in the video.
Wolf stated on her official Facebook page: "Have you all seen the Katy Perry marines video? It is a total piece of propaganda for the Marines… I really want to find out if she was paid by them for making it… it is truly shameful.
"I would suggest a boycott of this singer who I really liked – if you are as offended at this glorification of violence as I am."
'Part of Me' reached number one in the US and UK upon its release and is included as one of three new tracks on Perry's new repackaged album Teenage Dream: The Complete Confection
