The Girls Just Want To Have Fun singer appears on tonight's Graham Norton Show, where fellow guest Mark Wahlberg discussed how he has come to see the funny side of being so often confused with fellow actor Matt Damon.
Lauper, who has a very distinctive, high-pitched New York accent, said: 'It happens to me once in a while. I just sign Madonna. I don't care and as long as I don't talk I get away with it.'
The Time After Time singer and Madonna were pitted against each other as pop rivals during the 1980s.
Lauper and Wahlberg are joined on Norton's red sofa by Family Guy and Ted creator Seth MacFarlane and presenter Dara O Briain.
The Graham Norton Show airs on BBC1 at 10.35pm.
