The Eighties singer was recently in New York where she unveiled her own Gray Line New York double-decker bus outside The Metropolitan Museum of Art, where she filmed the video for Girls Just Want To Have Fun.
Speaking about Gaga, she said to OK!: 'I think that she's doing very well. I'm very happy for her. I think she's done a lot of great stuff and I wish her a lot of luck. I think the new artists; they work hard.
'It's the same like everybody. I'm glad to see that people care and are passionate about their work and she combines art and music. I always like that.'
Lauper was asked whether she believes some of Gaga's art and style was inspired by her.
She said: 'Well, everything is derivative in the end, isn't it? Nothing is really new. I think that she takes from Bowie, from me, from Grace Jones, from everybody.
'But hers is more like a sculpture. You know I think my favourite thing she did was when we did the amfAR benefit. it almost looked like a George Segal sculpture. I just loved that.'
