Prince Harry and Meghan Markle's baby girl is due on June 10 - the date which would have been Prince Philip's 100th birthday.
US sources close to the couple told The Sun the Sussexes may even name their daughter Pip as a tribute to Prince Harry's late grandfather.
"The baby is due on Philip's birthday and it would be so special if she came then. That, and naming her Pip, would be a lovely way to pay tribute to Philip," a source told The Sun.
The source says Prince Harry has been discussing the baby's due date and name ideas "quite openly" with his friends as the day gets closer.
Other name options include Lily, after Queen Elizabeth II's family nickname Lilibet, or after Prince Harry's mother the late Princess Diana who died in a car accident in 1997.
"They've been talking about Lily and Pip. They're not exactly traditional royal names, but these two aren't exactly a traditional royal couple," a royal source told The Sun.
The baby girl will be the couple's second child. Their two-year-old son Archie was born in May 2019.
Last month Prince Harry was dubbed as "bonkers" by Australian TV host Alan Jones after claiming Archie began saying "grandma Diana" shortly after learning to say "mama" and "papa".
"Prince Harry has teamed up with the new hero of woke Oprah Winfrey to produce a TV series called The Me You Can't See," Jones began in his rant against Harry.
"The series shows the pair opening up about mental health. In the first episode, Harry says 'I feel as though I'm outside of the system but I'm still stuck there'.
"He then says his son's first words were 'grandma Diana'. First words? Harry, have you gone completely bonkers under the Markle spell?" Jones asked.
