Lady Gaga is not a ''reductive Madonna copy'' and doesn't care what people say about her music, weight or past drug taking.
The 'Applause' singer doesn't care if people accusing her of imitating the elder star - sparked by her 2011 single 'Born This Way' bearing similarities to Madonna's 'Express Yourself' - because she feels her work stands apart.
She tweeted: ''LADY GAGA IS A REDUCTIVE MADONNA COPY! SHE'S OVER NOW! #WriteWhatUWant #SayWhatUWantBoutMe #ImNotSorry''.
She then added a link to a 2012 interview in which Madonna described her songs as ''reductive'', adding: ''MADONNA HATES GAGA SHE'S OVER. I don't need anybody's permission to be remembered. I will be. Whether they like it or not.''
Gaga, 27, also addressed her past issues with drugs and fluctuating weight in a similar manner.
She added: ''LADY GAGA IS ON DRUGS. HER CAREER IS OVER! (Been an addict for 10 years) #WriteWhatUWant. My recovery is a daily battle.''
She also tweeted a picture of her curvier figure accompanied by the ''#DoWhatUWantWithMyBody''.
Gaga also she didn't care the first single from her 'ARTPOP' album didn't reach Number One, adding: ''I write for the music, not the charts.''
Gaga's latest track, 'Do What U Want' featuring R. Kelly was released today (21.10.13).
