Hours after the outlet claimed they were told by Senior Buckingham Palace sources the Queen was "never asked" by the couple to use her cherished nickname for their baby, Harry hit back.
Using his and Meghan's close friend Omid Scobie to release a statement, the enraged prince insisted his grandmother was the first royal family member the couple called following their child's birth on Friday.
The statement also enforced that Harry and Meghan would have never given their daughter that name without Queen Elizabeth's permission.
He then took things up a notch by threatening legal action against the BBC.
Shooting down the reports, Harry and Meghan's statement read, "The Duke spoke with his family in advance of the announcement, in fact his grandmother was the first family member he called."
"During that conversation, he shared their hope of naming their daughter Lilibet in her honour. Had she not been supportive, they would not have used the name," it continued.

Following Harry's explosive clap back statement, BBC amended its report; however, their article still reads that the Queen was not asked by the couple for permission before using the name.
They announced the birth of Lilibet “Lili” Diana Mountbatten-Windsor on Sunday.
In their statement, they explained why they chose the unique name.
“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 statement from the couple's press secretary said.
Lilibet was Queen Elizabeth's childhood nickname and Prince Philip continued to lovingly call her it throughout their marriage.
After announcing Lilibet's birth, their archenemy Piers Morgan poked fun at the couple regarding their name choice amid the royal family feud.
Harry is still at odds with Prince William and Prince Charles after their ambush following Philip's funeral service.
