In the past, Lady Gaga has acknowledged that she owes a significant debt of gratitude to Madonna, and with good reason.
The 56-year-old Instagram exhibitionist was doing the whole blonde shock-pop thing before the Mother Monster was even born.
But apparently, Gaga hasn't spent enough time bowing before Her Madgesty's throne recently, because Madonna's latest desperate bid for relevance involves trying to rope the younger songstress into an inter-generational war of blonde hatred.
But after that it all seemed to die down, and Gaga likely assumed there was no more bad blood between mentor and protege. Of course she failed to take into account just how much Madge loves undeserved attention:
The Sun reports that Madonna slams Gaga in a recently recorded diss track entitled "Two Steps Behind Me."
The song - which may or may not wind up on Madonna's forthcoming album - includes lyrics like, "You're a copycat, where is my royalty."
Other tracks for the album reportedly feature shots aimed at Madonna's ex-husband, Guy Ritchie.
So, in this late stage in her career, Madonna has apparently decided to become a battle rapper. We guess that's better than her continuing to get naked on Instagram.
