The Material Girl has a longstanding grudge against Gaga's song 'Born This Way' because she reckons it has the same chord progression as her 1989 hit 'Express Yourself'.
How do we know this? Erm, because she's said it all before!
But that didn't stop Madge from having another go at Gaga, this time in an interview with a Brazilian TV station.
"I'm a really big fan of 'Born This Way'," she said, adding: "I'm glad that I helped Gaga write it."
Madonna has previously said Gaga's hit single was a "wonderful way to redo my song".
But Madge is also cashing in on the controversy, performing a mash-up of the two tracks during gigs for her current MDNA tour.
Could it be that the 53-year-old is trying to distract from her own questionable behaviour of late?
She's had three tour-related scandals in the last month alone — the latest saw the singer slammed for holding a gun to her head onstage just hours after the tragic 'Batman' shooting in Colorado .
In June she
mooned her audience in Rome and flashed a nipple during a concert in Istanbul .
Gaga has previously hit back at Madonna's plagiarism claims, saying the whole thing is "retarded" and "ridiculous".
We're just sick of hearing about it!
