Madonna's first two marriages didn't work out so well (to Guy Ritchie and Sean Penn, respectively). But is she considering a third walk down the aisle with Brahim Zaibat, her French dancer beau of two-plus years, who was still in diapers when she was prancing around in a cone bra?

So claims In Touch, which says the pop icon, 55, used the f-word (fiancé) in front of friends and her kids while introducing Zaibat, 25, at a Kabbalah service in New York on Sept. 4.

"She looked so happy and didn't try to keep it a secret," alleges a spy. "It was like she wanted everyone to know she was going to marry this man."

Considering that her split from Ritchie reportedly cost her north of $75 million, the Big M might be understandably wary of taking the plunge once again.

The official word? Her rep assures Gossip Cop that the engagement talk is "not true at all."
