Meghan Markle's father Thomas has claimed he heard about the birth of his granddaughter Lilibet Diana Mountbatten-Windsor on the radio.
The Duke and Duchess of Sussex's second child was born on June 4, with the couple announcing the news two days later.
In a trailer for Markle's upcoming interview with 60 Minutes Australia, he said he did not receive a phone call when the baby was born.
"No phone calls, I just heard it on the radio. I'll be very disappointed that I don't get to hold my granddaughter," he said.
He went on to state that he would speak about topics he has yet to discuss publicly in his bombshell interview, which is set to air on Sunday.
"You want dirty laundry? This is the first time I've ever discussed these things," the 76-year-old said.
Markle has been open with the press about his strained relationship with his daughter, revealing that he hasn't spoken to her since before her wedding to Prince Harry in May 2018.
Most recently, he rubbished claims made by the couple in their explosive interview with Oprah Winfrey in March
During an interview on Good Morning Britain, Markle was asked what he made of the revelation that a member of the royal family had asked about the skin color of the couple's son Archie, before his birth in 2019.
Markle claimed that the "whole thing about color and the baby's skin color is bulls***." He added that he doesn't think the royal family is racist.
His interview in Australia follows a media storm over baby Lilibet's name.
The statement from the couple released on June 6 read: "Lili is named after her great-grandmother, Her Majesty The Queen, whose family nickname is Lilibet. Her middle name, Diana, was chosen to honor her beloved late grandmother, The Princess of Wales."
The nickname Lilibet was given to the queen during her childhood as she could not pronounce "Elizabeth."
On June 9, the BBC reported a claim, attributed to a palace source, that the couple had "never asked" the queen's permission to use the name.
However, a spokesperson for Harry and Meghan told Newsweek that the duke had "shared their hope" of naming their daughter Lilibet with the queen, ahead of the announcement.
"Had she not been supportive, they would not have used the name," the spokesperson added.
Prince Harry and Meghan have since called in their legal team at Schillings over the BBC report.
The lawyers have distributed letters to the British media stating that the allegations are defamatory and consequently "should not be repeated."
