No doubt Gwen Stefani is in haute water!

The gorgeous rock star is in the middle of a couture crisis.  The gown she wore to last week’s amfAR gala at Cannes and then auctioned off for charity is in the middle of a high fashion he said-she said.

The lacy black dress she wore on a L’Oreal photo shoot earlier in the day went for $125,000 at the amfAR ball, and was billed as “a creation of her own, by L.A.M.B.”  But now Michael Angel has stepped forward to claim ownership.
