Hollywood megastar Leonardo DiCaprio helped rescue a 24-year-old Club Med cruise worker who fell overboard in the Caribbean.

The Oscar-winning actor was on a luxury boat near St. Bart’s when it picked up a Mayday call, prompting him and his friends to search for the Frenchman.

The group eventually found the man who had been treading water for 11 hours near the island of Saba, part of the Leeward Islands.

The captain of DiCaprio’s boat reportedly put the man’s chances of survival “at one in a billion”.

DiCaprio’s boat rescued the man and provided him with food, drink and clothes before returning him to coastguards.

“Leonardo played a blinding role in his own real-life Hollywood movie,” a source told The Sun. “[DiCaprio’s crew] were the only responders, and his only chance of survival, despite being hours away.

“The ‘man overboard’ was minutes from drowning when he was found.”
