Maintaining such a perfect public presence has been hard. Gaga says she hid from her fans when she was confined to a wheelchair after a hip operation this year.
Now the pop superstar is back, to promote her latest album, ARTPOP.
She has relaxed her crazy outfits and become more comfortable outside, but said she was tired of people telling her that "she's finished".
"It's literally not even been two weeks since my first single came out and it's all, 'She's over', or because I'm not No. 1 yet, 'She's finished'.
"People focus less on the music and focus more on how the music's doing; how it's faring from a numbers perspective, from a financial perspective. If you think I give a damn about money then you don't know me as an artist at all."
She added: "I think that once you've had a few No. 1s in your career that you've kind of proven yourself and I don't feel the need to prove anything anymore."
A few weeks ago, Gaga tweeted a Michael Jackson quote: "The bigger the star, the bigger the target."
She told The Guardian: "It gives them a sense of pleasure when they believe that they've destroyed me or taken me down. It's almost entertainment for people to poke fun at Lady Gaga, but at the very same time they have no idea the album I've made."
