Marc Anthony -- My Hot Ex-Wife Costs Me $16,500 a Month

Marc Anthony's Miss Universe ex-wife has been living off the singer's gravy train for eight years -- because ever since the former couple divorced ... Marc's been paying her a staggering $16,500 per month in alimony and child support.

A judge in the Dominican Republic issued the alimony and child support order in 2004 -- when the divorce was finalized -- and now, for the first time, the order has been made public.

Marc's ex Dayanara Torres -- who recently moved to the U.S. -- had to file the order in an L.A. court so that she can enforce it on her new home turf.

According to the court docs, obtained by TMZ, Marc's been ordered to pay $3,500 USD a month in alimony to Torres -- and an additional $6,500 per month in child support for each of their two sons. All told, the bill is $16,500 a month.

Anthony and Torres were married back in 2000 in Vegas. Their two sons -- Cristian and Ryan -- were born in 2001 and 2003 respectively.

A week after their divorce was finalized in 2004, Marc married Jennifer Lopez.
