Gisele Bundchen's charm was no match for the President of France.

The Brazilian supermodel met Emmanuel Macron Tuesday during a meeting of the Global Pact for the Environment at the United Nations Headquarters in NYC. They exchanged pleasantries and shook hands in a move that can only be described as both classy and gentlemanly of Macron.

Unclear what Gisele said to him ... but he blushed like a little boy meeting his first crush.

No wonder she was in a rush ... can't leave the Prez hangin.
