Oscar de la Hoya has been dumped as brand ambassador for tequila Tres Generaciones after he went to rehab. Beam Global Spirits & Wine announced the deal in May — right before the troubled boxer went to rehab — trumpeting that he “epitomizes so many of the same traits and qualities of Tres Generaciones.” Oops. A rep for the firm now tells us, “We have severed all ties with Oscar because of his personal issues. We didn’t know he had these issues until we had announced the deal and money changed hands. Those issues became clear shortly after, and so the deal never really got off the ground. We advocate responsible drinking. I suppose we should ask for our money back.”
