A British man and a Canadian woman plunged 12 feet to the ground when a balcony collapsed from under them as the two were in the heat of a “passionate” sex session at a resort in the South of France, according to a new report.

The unidentified 30-year-old man was left gravely wounded from the fall, while the 28-year-old woman – who was also unidentified — only suffered minor injuries, The Sun reported.

The incident happened Saturday afternoon at the French Riviera seaside resort of Le Cannet, north of Cannes, according to the news outlet.

“There was a balcony collapse during the lovemaking,” a source told The Sun. “Large fragments of the stone balcony surrounded the couple after the fall.”

“They were becoming very passionate indeed, and suddenly toppled from the first floor of the villa into the street below,” said the source.

The source said the couple was “making love in an open view” when the balcony suddenly “gave way,” the news outlet reported.

The woman seemed to suffer less serious injuries than her paramour because she was cushioned by him during the fall, the source told the site.

Neighbors quickly called emergency services following the incident.

Medics rushed the man to an intensive care unit at the Pasteur Hospital in Nice, where he was listed in critical condition, according to The Sun.

The woman was “hurt, but stable,” the news outlet reported.

One local told the site that the lovers were “having a great time, all day and all night,” before the tragic fall.

“This was absolutely fine because they were enjoying themselves on holiday, but nobody expected anything like this,” the local said.

According to The Sun, investigators initially were looking into whether alcohol or drugs played a role in the incident, but are now investigating the safety of the building.

Under French law regarding vacation rentals, the owners could face prosecution over the plunge, the paper reported.
