The couple reside in Berkshire, and as well as their new bundle of joy, they live with their adorable pet dogs Zulu, Inka, Luna, Mabel and Nala. We've seen glimpses of their dreamy estate on Instagram - and it looks like the perfect place for their family.
James and Alizee, who met by chance in South Kensington in 2018, previously shared a house in London, but they ditched the city in favour of the countryside. In fact, James revealed their furry friends were actually one of the reasons they chose a rural lifestyle.
Ahead of their move, James wrote in The Telegraph: "We are country people and love going out for long walks, but one of the key reasons we wanted to live in the countryside was our six dogs."
James has shared a few looks inside his private home life with sweet photos of Alizée and their pets. Take a look at their stunning country house, as well as their former London property and James' parents Carole and Michael Middleton's Berkshire home where the couple spent time during the pandemic…
Sharing a snap of himself, Alizée and one of their pet dogs outside the red brick exterior, he wrote: "I think buying a house is up there with one of the most stressful experiences in my life.
"It’s been a hectic few months moving into our new home & we couldn’t be happier. We are settling into our life in the country & the dogs their new home #housemove #lifeinthecountry #dogsofinstagram #dogs."
James Middleton's living room
In keeping with the rustic property, the couple's open plan living room features a chunky wooden dining table, beams on the ceiling and a cast iron fireplace with a brick surround where their dogs posed for a photo.
Back in 2017, James posted a photo of one of his dogs as a puppy in the living room of his former home. He inadvertently showed that the room had olive green walls and wooden floors, as well as a traditional fireplace with green and cream tiles. There was wooden panelling along various areas of the walls, as well as a vintage oak piano.
It had a large open fireplace with a black stone back, and traditional logs. It was framed with a cream leather ledge and black railing to protect his dogs.
James Middleton's dining room
James is the proud owner of one golden retriever and five black spaniels, and he treats them to a la carte dinners at home. In March, he shared a photo of them sat around his wooden dining table, and revealed that the room was decorated with cream walls and a large mirror hanging in a wooden frame on the wall. His reflection also shared a peek at his staircase, which seemed to have black steps and a matching bannister.
James Middleton's swimming pool
James shared several photos of his dogs and Alizee enjoying the outdoor swimming pool which is believed to be at Carole and Michael's home. It's built with white tiles and framed with tall bushes for privacy.
A different photo of another of his dogs jumping into the pool showed that there is also a white bench at one side of the pool.
James Middleton's garden
A photo of one of his dogs unveiled the garden at his parents' home, which has a big lawn and plants growing up the exterior of the house.
