"It was good to clear the air and it was amicable," Warne told the Daily Telegraph.
During England's 5-0 Ashes series loss 'Down Under', Cook's generally conservative approach came under fire from the legendary leg-spinner.
Warne had called Cook 'boring' in one his columns and the Englishman had reacted by saying that, "something needs to be done" to these personal remarks by the Aussie.
But on Thursday, Warne decided to call truce and speak to captain Cook personally.
"We spoke for about an hour about lots of different things. I had my say, he had his say. He told me how he felt and I told him how I felt about certain things," said Warne.
Cook though has also been criticised for his defensive approach by fellow countryman Geoffery Boycott, stating that the 29-year-old "won't make it as a tactical captain".
