James Middleton welcomes first child! Kate’s brother and his wife Alizee Thevenet are spotted walking newborn in £795 Silver Cross pram in Notting Hill

The Princess of Wales’ brother James Middleton has welcomed his first chid with wife Alizee Thevenet.

The entrepreneur, 36, and French financier, 33, were spotted going for a walk with the newborn in Notting Hill on Tuesday.

The baby – whose gender has not been revealed – is the first cousin of Prince George, Princess Charlotte and Prince Louis and the niece or nephew of Kate and William.

The parents have kept the exact details and date of the baby’s birth private. It’s believed he or she was born in recent weeks as James shared a snap of his then-pregnant wife on September 12th to celebrate their anniversary and declare: ‘the best is yet to come’.

Already a doting dad, James fit right in with the west London set as he pushed a £795 Silver Cross pram while sporting an autumnal ensemble of navy chinos, brown boots and a green jacket.

He added a yellow scarf to brighten up the look, while Alizee proved she was a cool mum in a double denim look with a blue shirt and jeans which she paired with a 1970s-inspired brown suede coat and fur gilet.

Keeping her blonde hair long and loose, the French financial analyst showed off he natural beauty in a make-up free look while clutching a shopping bag and cup of coffee.

Slung in the bottom of the pram was a travel bag from Sezane – which costs around £127. The brand is a favourite of Princess Kate’s.

The couple, who live near where Kate, sister Pippa and James grew up in Bucklebury, Berkshire, strolled along Westbourne Grove in Notting Hill.

James announced Alizee’s pregnancy on Instagram in July, where he shared a snap of his wife in a olive green dress with their dog Mable in a gorgeous countryside setting. 

‘We couldn’t be more excited … well Mable might be,’ James wrote, before referencing his tough year following the death of his dog Ella.

‘It was a very difficult start to the year after losing my beloved Ella however we will end the year with the most precious little addition to our growing family’.

It’s likely that Kate will certainly welcome becoming an aunt again, as she has mentioned she is ‘feeling broody’ on many occasions.

James and Kate’s sister Pippa has also has three children with her husband James Matthews: – Arthur, Grace and Rose – meaning the new addition will be the seventh grandchild of Carole and Michael Middleton.

Ella is James’ beloved spaniel, who died last year aged 15. 

Writing in The Telegraph in 2021, James explained he met Alizée in 2014 at Chelsea’s the South Kensington Club when Ella ‘made a beeline for Alizée’.

James, who was ’embarrassed’, went over ‘to apologise and bring Ella back’, recalling how Alizée thought he was a ‘waiter’ and ‘ordered her drink while continuing to stroke Ella, who at this point was on her back lapping up the attention.’

He has previously credited the black spaniel with helping him overcome his mental health struggles and introducing him to his wife .

In January 2019, James explained in a personal essay for the Daily Mail how Ella had helped him through his depression battles.
