Madonna is set to tackle the issue of Lady Gaga's 'homage' to her head on this Summer, with leaked rehearsal footage showing that she is set to perform a mash-up of her song 'Express Yourself' and Gaga's 'Born This Way'.
There is no denying that the two songs sound very similar but Gaga, however, has always maintained that the two songs share nothing in common.
Madonna, though, clearly feels different and there is no way the mash-up seen below can be taken as anything other than an attack on what she perceives to be a rip-off her original.
Gaga has previously stated that comparisons between her 2011 hit and the 1989 Madonna track are 'retarded'. Madonna, meanwhile, says she finds the Gaga track 'interesting'.
You can see the mash-up video, which also includes a bit of 'She's Not Me' from Madonna's the 2008 album Hard Candy, below.
