"You know, you're in such good shape," President Trump said to Brigitte Macron in a video the French government posted to its official Facebook page.
"Isn't she in such good shape?" Trump, 71, said to President Macron, before adding of Madam Macron, "Beautiful."
The Associated Press was the first to note this exchange.
The U.S. president and the French first lady had their own handshake moment earlier.
When the Trumps first arrived at the Les Invalides, Trump and Brigitte Macron greeted one another with a kiss on each cheek. Trump then grabbed Macron's right hand, jerking it toward him, as she tried to step back.
