French is the language of love - now a glamorous air kiss between US First Lady Melania Trump and Canadian Prime Minister Justin Trudeau at the G7 summit in Biarritz has sent the internet alight with its sense of European glamour.

FLOTUS was captured raising her face to give Trudeau a peck on the cheek during the leaders' family photograph at the at the G7 in Biarritz on Saturday.

But the combination of President Trump standing next to her with his eyes downcast and French President Emmanuel Macron and First Lady Brigitte Macron watching on, led viewers to dub it like a "Vogue ad" for its glamour and comic overtones.

It led to #MelanialovesJustin trending on Twitter and sparked comparisons to a previous picture of Ivanka Trump "swooning" at the Canadian leader.

Body language expert Judi James told the Express the "pitch-perfect ritual" is made more dramatic by the camera angle.

"With her husband's hilarious over-pucker as he leant to cheek-kiss Angela Merkel, Melania showed the smooth way to approach the ritual with the very charming Trudeau, with the pair ending up looking like a Vogue ad while Trump stared grimly in the background," she said.

It's not the first time Justin Trudeau has led the internet to swoon, with images of him doing push ups, taking selfies and as a younger man also going viral.
