The exes ended up on stage for Madonna's charity event -- Raising Malawi -- during Art Basel in Miami. She told the crowd she'd marry Sean again if he bid $150,000 for a necklace, and he did.
He was outbid for the jewelry. As for the marriage part? The jury's still out.
Watch what happened when Madge called Sean on stage -- she's professed love, but she's done this kinda thing before.
