Marc Anthony Rails on the Stand -- It'd Be 'Tragic' To Pay Her More Child Support

Marc Anthony should change his name to Shakespeare after the drama that just unfolded on the stand in his bitter child support case -- he said it would be "tragic" to pay his ex-wife more child support than he's already giving her.

Marc took the stand Friday, claiming the increase in child support Torres is seeking -- from $13,000 a month to $113,000 -- would be detrimental to his and Torres' children because it's simply excessive.

Anthony insisted he already pays all the costs in relation to his children's needs.
