Madonna has made a new dig at Lady GaGa in relation to her track ‘Born This Way’.GaGa came under scrutiny when the song was first released, due to it sounding similar in parts to Madonna classic ‘Express Yourself’.However, GaGa dismissed the accusations, saying that claims the song was based on Madonna’s track were "retarded”, although she later apologised for her choice of words.Madonna has now quipped in an interview on Brazilian television. "I’m a really big fan of [‘Born This Way’]. I’m glad that I helped GaGa write it.”Madonna has previously made fun of the comparison by performing a mash-up of the two tracks during her ‘MDNA’ tour.Lady GaGa has yet to publicly comment on Madonna’s comments, but recently made a speech on stage about general criticism of her work.
