French President Emmanuel Macron’s visit to Vietnam was overshadowed by a viral moment with his wife, Brigitte Macron. As the couple prepared to disembark in Hanoi, footage showed Brigitte appearing to slap or brush her husband’s face, surprising the president. Macron quickly composed himself and waved to cameras.

The incident sparked social media debate. Moments later, Brigitte declined to hold Macron’s hand while descending the plane stairs. Macron is scheduled to continue his Southeast Asia tour with visits to Indonesia and Singapore.
