Prince Charles is 'extraordinarily fond' of Meghan Markle, 'over the moon' to become grandfather again

Like all royal fans, Prince Charles is eagerly awaiting the birth of Baby Sussex.

A source close to the royal family tells ET that Prince Harry's father, Prince Charles, is "over the moon" about becoming a grandfather again, after already being a granddad to his older son Prince William's kids with Kate Middleton -- 5-year-old Prince George, 3-year-old Princess Charlotte and 1-year-old Prince Louis.

Prince Harry's sweetest and funniest comments on fatherhood

May 2012

"I've longed for kids since I was very, very young. I'm waiting to find the right person and someone who's willing to take on the job," he said to Katie Couric in an interview. 

October 2015 

"No matter how old I am I will always have the kid inside me," he said while in New Zealand. "I’m obsessed with children. I don’t know if they like me but you know they are great fun and you can never really say no to them.”

March 2016

"We will do everything we can to make sure that she's never forgotten and carry on all the special gifts, as such, that she had and that she portrayed while she was alive," he said to Robin Roberts during an interview for the Invictus Games. "I hope that a lot of my mother's talents are shown in a lot of the work that I do." 

He continued: 

"I hope she's looking down with tears in her eyes being incredibly proud of what we've established. I'm sure she's longing for me to have kids so she can be a grandmother again. I hope, once again, that everything we do privately and officially that it makes her proud." 

March 2016

“I can’t wait for the day [to have children]. It will be fantastic. I adore kids. I enjoy everything they bring to the party," he said to Robin Roberts. 

June 2017

"I am determined to have a relatively normal life, and if I am lucky enough to have children, they can have one too,” he commented in an interview

October 2018 

 "Thank you for the incredibly warm welcome and the chance to meet so many Aussies from all walks of life...we also genuinely couldn't think of a better place to announce the...upcoming baby, whether it be a boy or a girl," he said after the couple's pregnancy news broke on their royal tour of the Pacific. 

October 2018 

"From myself and my wife and our little bump, we are so grateful to be here. We bring blessings from my grandmother the queen and our family," he also said in a speech during their visit to New Zealand. 

January 2019 

“As someone who is about to become a father, I am acutely aware of our shared responsibility to make this world more resilient and its inhabitants more accountable for the next generation,” Harry said in a speech at Lancaster House in London. 

February 2019

"What? You're pregnant?" Prince Harry joked to Meghan while in Morocco. "Is it mine?" he continued.

The source notes that Charles is particularly a big fan of his daughter-in-law, Meghan Markle, whom he walked down the aisle at her and Harry's wedding at Windsor Castle last May. Since then, the two have been snapped smiling and joking together at royal events, obviously enjoying one another's company.

"Charles is extraordinarily fond of his new daughter-in-law Meghan," the source says, adding that he is looking forward to the big day Meghan gives birth and can't wait to meet Harry's firstborn.

Earlier this month, Meghan and Harry made the move into their new home at Frogmore Cottage at Windsor Castle, after previously living at Kensington Palace, where Will and Kate also reside. Our source says that one of the reasons for the move to Windsor was the opportunity to bring their baby up away from the “prying eyes of the paparazzi." But according to the source, Meghan and Harry have already been welcoming family as guests in their new home, which will continue when the baby comes. The source says a series of Meghan's closest friends have recently been to London to visit, and she has more visits scheduled after the baby.

It has been "a time filled with love and excitement," the source says of the couple eagerly awaiting their first child.

As for Meghan and Harry's plans for when the baby arrives, the source says the couple has opted to have a lower-profile birth in order to celebrate privately as a family first. Earlier this month, Kensington Palace revealed that Meghan and Harry are breaking with protocol regarding the arrival of their first child, and won't be immediately announcing the birth of the baby. Additionally, unlike Prince William and Kate Middleton, who posed for photos outside St. Mary's Hospital following the arrival of their three children, Meghan and Harry will have a photo op with their newborn on the grounds of Windsor Castle when they are ready.

The Sussexes "want to spend time with family and enjoy the first special days of their baby's life," the source says, adding that the public will have less access to Baby Sussex than George, Charlotte and Louis because the child is not directly in line to the throne.

A source recently told ET that Meghan is due "any day now." In addition, two sources recently told ET that Meghan's mother, Doria Ragland, has already arrived in London.
