The 56-year-old singer has allegedly taken a swipe at her ex-husband, whom she married in 2000 and divorced in 2008, in leaked lyrics taken from her upcoming 13th studio album.
She sings of the director in the song 'Heartbreak City': ''Cut me down the middle, f***ed me up a little. You said I was your queen. I tried to give you everything. And now you want your freedom.
''You got just what you came for, a bit of fame and fortune, and I'm no longer needed. You tore me into pieces, you didn't have no damn reason. I let you in my kingdom, you helped yourself with everything.
''I curse the day we met. This memory is haunting me. I wish I could forget.''
However, Guy, 45 - with whom she has sons Rocco and David - isn't the only one Madonna has hit out at in her songwriting as she's also criticised the 'Applause' hitmaker, 28, for ''copying'' her.
In the track 'Two Steps Behind Me', she sings: ''You're a copycat, Where is my royalty? You're a pretty girl, I'll give you that. But stealing my recipe, it's an ugly look.
''Did you study me hard enough? You're never gonna be, you're just a wannabe me. Like a sister all messed-up, who's gonna help you out?''
Meanwhile, there's no guarantee that either of the songs will make it onto the album as the 'Hung Up' hitmaker has penned around 50 tracks for the collection, but friends of the blonde beauty insist she isn't holding back when it comes to her songwriting.
A source told The Sun newspaper: ''They're very harsh lyrics but Madonna really wants to express herself again.''
