Pippa Middleton takes four-month-old baby Grace out for a stroll in Chelsea

Pippa Middleton appeared to be suffering from the sleepness nights that plague all new mothers yesterday as she was spotted looking a little heavy-eyed out on a stroll with new baby Grace.

The Duchess of Cambridge’s sister, 37, caught a few evening rays as she pushed her four-month-old daughter in a navy stroller along the streets of Chelsea, south west London.

Already mum to son Arthur, two, she and multi-millionaire financier husband James Matthews, 45, welcomed little Grace in March. 

Pippa looked chic in a long check button-down dress in shades of blue, which tied at the waist.

Opting for a casual look, she teamed it with white tennis-style trainers and whisked her brunette locks back into a messy bun.

Pippa kept her make-up natural and sported minimal jewellery – bar her large 3.5 carat £200,000 diamond engagement ring and a delicate necklace. 

Socialite Pippa is often seen out and about walking her children and dogs in south west London, though yesterday evening she opted to leave her pets and eldest son at home. 

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

Passers-by could see her show her proficiency in urban cycling as she confidently indicated her turns to nearby cars. 

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

They also made an appearance at the European Championships semi-final match at Wembley, keeping a relatively low profile as they cheered on England who triumphed over Denmark.

Pippa and James were seen queuing alongside punters to enter the event and did not join their brother-in-law Prince William in his box.

Kate Middleton was unable to attend that match, having been forced to self-isolate after she came into contact with someone who tested positive – despite being double-jabbed and testing negative for the virus herself.

Grace was born in the early hours of 15 March, weighing 6lbs 7oz. 

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

Rumours of Pippa’s pregnancy first swirled shortly before Christmas when Page Six reported the couple were expecting another baby.

A source close to the Middleton family told the publication in December Kate’s sister was expecting, saying: ‘Pippa and James are thrilled, it’s fantastic news amid a difficult year. The entire family is delighted.’

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

Pippa began dating James in 2016 and the two tied the knot in May 2017. The racing driver-turned city trader, who was privately educated at Uppingham School, is set to inherit the Scottish courtesy title of ‘Laird of Glen Affric’ which came with the 10,000-acre estate of the same name near Inverness that his father bought in 2008. 

James is listed as managing director of Beaufort Glen Affric. He owns a £3m private jet and bought a six-bedroomed, £17m house in 2014, which boasts a car-stacking garage in the basement, along with an underground home cinema and a lift.
