Naomi Campbell called on Argentina's first elected female president Friday, and the pair discussed the release of two women held hostage for years by Colombian guerrillas, the state news agency said.

President Cristina Fernandez had forcefully lobbied alongside Venezuela for a hostage release and dispatched husband and former president Nestor Kirchner on a humanitarian bid to the Colombian jungle.

That mission failed to bring back the two hostages by New Year's Day, but they were liberated Thursday after being held for six years by the Revolutionary Armed Forces of Colombia, or FARC.

Campbell recently conducted a celebrity interview with the key hostage mediator and leftist Venezuelan President Hugo Chavez. The supermodel's interview as a contributing editor for the British edition of GQ appears in February's edition.
