French rock star Johnny Hallyday dies at 74

France's biggest rock star Johnny Hallyday, who had lung cancer, has died, BBC News reports, citing his wife.

Hallyday was 74.

The singer - real name Jean-Philippe Smet - sold about 100 million records and starred in a number of films.

He was made a Chevalier of the Legion D'Honneur by President Jacques Chirac in 1997.

The French simply called him "Our Johnny". However, outside the Francophone zone, Hallyday was virtually unknown.

In a statement, his wife Laeticia said: "Johnny Hallyday has left us," according to the AFP news agency.

"I write these words without believing them. But yet, it's true. My man is no longer with us.

"He left us tonight as he lived his whole life, with courage and dignity," she said.

Reacting to the news, French President Emmanuel Macron referenced the title of a recent tribute album by saying: "There is a little bit of Johnny in all of us."

"Across generations, he carved himself into the lives of French people," Mr Macron said. "He charmed them through the generosity you saw in his concerts: so epic, so intimate, in huge venues, in small spots."

Among those to pay tribute was American guitarist Lenny Kravitz.
