She opted for a casual look, paired it with tennis-style white sneakers and swung her dark brown locks back in a messy bun.

Pippa kept her makeup natural and wore minimal jewelery – except for her large 3.5 carat £200,000 diamond engagement ring and a delicate necklace.

Socialite Pippa is often seen walking her children and dogs in south-west London, although last night she chose to leave her pets and eldest son at home.

Last month she was seen expertly making her way through Chelsea’s traffic on a stylish black bike, wearing a light blue dress and helmet.

Passers-by could see her displaying her prowess at city biking as she confidently pointed her turns to nearby cars.

She was also spotted on Center Court at Wimbledon earlier this month enjoying a rare daytime date. The couple watched the men’s semifinal between Italy’s Matteo Berrettini and Poland’s Hubert Hurkacz.

They also made their appearance in the European Championship semi-final at Wembley, keeping a relatively low profile as they cheered on England’s triumph over Denmark.

Pippa and James lined up next to gamblers to participate in the event and did not join their brother-in-law Prince William in his box.

Kate Middleton was unable to attend that match because she was forced to self-isolate after coming into contact with someone who tested positive – despite getting a double shot and testing negative for the virus herself.

Grace was born in the early hours of March 15th and weighed 6lbs 7oz.

Grace’s middle names – Elizabeth Jane – are a nod to her grandmothers, Carole Elizabeth Middleton and Jane Matthews, while Elizabeth may also be a subtle acknowledgment of the family’s royal ties.

Rumors of Pippa’s pregnancy first made the rounds shortly before Christmas when Page Six reported that the couple was expecting another baby.

A source close to the Middleton family told the publication in December that Kate’s sister was pregnant and said: “Pippa and James are excited, it’s fantastic news in a difficult year. The whole family is delighted.’

Pippa never commented on the pregnancy and instead kept a characteristically low public profile.

Pippa started dating James in 2016 and the two tied the knot in May 2017. the 10,000-acre estate near Inverness that his father bought in 2008.

James is listed as general manager of Beaufort Glen Affric. He owns a £3 million private jet and in 2014 bought a £17 million house with six bedrooms, a garage in the basement, an underground home cinema and an elevator.
