Pippa Middleton is seen for first time since pregnancy reports

Pippa Middleton headed out for a walk with her two-year-old son after it was reported she is expecting her second child with husband James Matthews.  

Wrapped up against the cold in a navy coat, Pippa, 37, held son Arthur’s hand as they strolled down a leafy west London street earlier today. 

It is the first time the Duchess of Cambridge’s younger sister has been seen since it was reported she is pregnant with her second child. 

Pippa and James, who tied the knot in 2017, are said to be ‘thrilled’ that Arthur will soon have a younger brother or sister.

A source close to the Middleton family told Page Six: ‘Pippa and James are thrilled, it’s fantastic news amid a difficult year. The entire family is delighted’.

The couple declined to comment on the reports.

Certainly Pippa appeared in good spirits as she strolled through London with her son, chatting and holding his hand.

Two-year-old Arthur, who’s a first cousin of Prince George, Princess Charlotte, and Prince Louis, looked adorable in a navy coat and trousers.

It comes as amid news the couple have prepared to snap up 72 sprawling acres of land in leafy Berkshire for just £1.5million – in a village where a detached house with a garden already costs close to that price. 

Hedge fund billionaire James, brother of reality TV star Spencer Matthews, and author Pippa currently reside in a £17 million six-bedroom home in London.

They are thought to have grand designs on a home in Bucklebury, which is just a stones throw away from the Middleton family home in Chapel Row – where Pippa grew up with big sister Kate, 38, and younger brother James, 33.

Pippa’s parents, Carole, 65, and Michael, 71, still live in a £5million home, a price tag that is much more indicative of what a discerning buyer might expect to pay for a country home.

As well as a trio of royal cousins from their aunt Kate, the new Middleton-Matthews baby will also have cousins on their father’s side. Theodore Frederick Michael, two, and Gigi Margaux Matthews, five months, who former Made in Chelsea Lothario Spencer shares with his Irish model wife Vogue Williams.

The Matthews family owns the Eden Rock resort on St Barts, one of the region’s most exclusive hotels beloved by many famous faces.

Stars including Elton John, Brad Pitt and Leonardo DiCaprio have stayed at the resort, where suites can cost up to £25,000 a night.
