Kensington Palace tweeted overnight that Kate and William will spend the festive season supporting deployed military personnel and their families.
The decision is supposedly due to the fact that the royal couple is expecting their firstborn in the spring of 2019.
According to Metro UK, Frogmore Cottage is now uninhabited, but "has been a favourite royal hideaway for over 300 years".
Instead, the couple is returning to the grounds of Windsor Castle, where they Wednesday in May, and will be moving into Frogmore Cottage, a home on the Windsor estate.
With ten-bedrooms, there is plenty of privacy and space at the Grade II listed building which is now undergoing a multi-million pound refurbishment.
"The home is said to be a gift from the Queen", reports Metro UK, noting that it's just 20 miles away from their current digs.
"But there has been a bit of tension between the brothers".
Frogmore is now uninhabited and is only used by the Royal family for private and public functions. It is near Frogmore House, the grand 17th century manor house where Meghan and Harry held their evening wedding reception for 200 friends after their nuptials earlier in the day. The large home is reportedly set to undergo a big refurbishment to turn it from staff accommodation into a family residence. It is believed they will be remodelled and transformed into a more family-friendly home.More news: Sidhu expresses gratitude to PM Imran for opening Kartarpur border

The sprawling grounds allowed Queen Charlotte to indulge her love of botany, as the garden was filled with many rare and unusual plants.
Windsor Castle is one of Queen Elizabeth II's favorite homes.
The Berkshire countryside offers peace and seclusion, although it is now possible to walk right up to the front gate at Frogmore Cottage.
Frogmore House was once home to Queen Victoria's mother, the Duchess of Kent, for nearly 20 years. She spent long periods there after the death of her husband and her favourite "Munshi" (teacher) Abdul Karim, once lived at Frogmore Cottage.
Frogmore House is only open to members of the public on three days per year, when all proceeds are donated to charity.
Kensington Palace said Saturday that Harry and Meghan, the Duchess of Sussex, will move from Kensington Palace in central London to Frogmore Cottage, a house on the grounds of Windsor Castle, early next year.
Harry and Meghan have lived in Nottingham Cottage, in the grounds of Kensington Palace, since their engagement in 2017.
