Hallyday, 69, fell ill last weekend at a home he owns on the island of Saint-Barthelemy. He left a hospital in Fort-de-France early Friday and flew by private jet to Los Angeles where he is expected to check into another medical center.
RFI said it was unclear whether he will be well enough to go one with his 2012 tour, the second leg of which is due to begin in October in Montreal.
