The pop legend has revealed she experienced a bizarre night-time fantasy about hooking up with the Hollywood hunk and having his blonde babies.
During a no-holds barred online text Q&A with fans on Reddit.com, Madonna said: [''I last laughed at] The fact that i had a dream about brad pitt. (sic)''
The 'Ray of Light' singer clearly couldn't get the handsome father-of-six - who is engaged to Angelina Jolie - out of her head since she brought up the incident again later on in the chat.
Madonna, 55, quipped: ''Brad Pitt and I were living together and there was a small blonde child in the bed. Sorry Angelina, it was only a dream.''
The 'Material Girl' singer was exceptionally honest with her fans during the online grilling session.
Quizzed about what her best ever birthday present was, Madonna cheekily quipped: ''I got a bong in the shape of a penis''.
Her admirers were intrigued and bombarded her with follow-up questions about how she uses it, with one fan suggesting, ''paperweight''.
The mother-of-four also touched upon her children's upbringing, joking she wouldn't let her 13-year-old son Rocco - who performed as a back-up dancer on the pop star's recent 'MDNA' tour - start a pop career until he finishes school.
Asked whether the talented teen was due to release an album of his own, Madonna replied: ''He wishes! Just need to get him thru the 8th grade right now. get him to do his math homework! (sic)''
However, the question that attracted the most controversy was undoubtedly the enquiry about what she really thought of her younger pop rival Lady GaGa.
After Madonna remained silent, her fans speculated, ''The silence is deafening'', with another commenting, ''Yep. Got my answer. Loud and clear.''
