Madonnahas reportedly taken a cheeky swipe at Lady GaGa in rehearsals for her MDNA tour, singing the lyrics to GaGa's Born This Way as she performs her own Express Yourself.
The playful dig follows claims that GaGa's song sounded suspiciously similar to Madge's pop classic, and footage of the Queen of Pop's rehearsal in Israel have surfaced on YouTube, reports Digital Spy.
After singing the lyrics to Born This Way, Madonna then shifts into She's Not Me from her 2008 album Hard Candy. Is she planning on sending a none-too-subtle message to fans in her actual concerts?
When quizzed about the similarities between the tracks before GaGa said comparisons were "retarded" (before apologising for using that word).
Madonna has previously told The Daily Beast: "I thought, 'What a wonderful way to redo my song'. I mean, I recognised the chord changes. I thought it was… interesting."
