Prince Harry and Meghan Markle reportedly slept through calls from the US Embassy as officials tried to inform them about Prince Phillip's death.
It has been claimed the Duke of Sussex was unaware of his grandfather's death until police turned up at his and Meghan's £11 million home to let them know of his passing.
Prince Phillip, the Duke of Edinburgh died on April 9 at Windsor Castle, with officials at the US Embassy then trying desperately at 3am local time to reach Harry at his mansion in Montecito, California.
It's unknown if the couple's telephone ringer was switched off, but, reports TMZ, an Embassy representative then called the Santa Barbara Sheriff's Department and asked if someone could drive over to Harry and Meghan's residence to let them know the sad news.
A police officer then spoke to one of the couple's staff members at the gate and Harry, 36, was asked to urgently call the Embassy, the news outlet claims.
A Palace source told our sister paper The Mirror how the Sussexes were contacted about Philip's death was a private matter and would not comment further.
Following the news, Harry flew back to Britain for Philip's funeral on April 17, in the midst of controversy over the bombshell Oprah Winfrey interview he and Meghan had taken part in weeks before.
