Catherine wowed everyone after her guest editorship to the Huffington Post UK on Wednesday morning, but later that day it was back to tending to her own royal brood.
Leaving the tiara and title at home, the 34-year-old opted for a casual look as she hit up the shops on King’s Road in Chelsea.
Onlookers notice the royal opted for black yoga trousers, a black coat and scarf and red running trainers.
The mum-of-two ducked into luxury fitness shop, Lululemon for some well-deserved retail therapy. And some athletic wear won’t go astray as Catherine is set to take part in a tennis workshop with Andy Murray’s mum, Judy.
The brunette royal and the new granny will visit Craigmount High School on their way up to Edinburgh as they take part in the Tennis On The Road coaching clinic.
Judy founded the foundation, which aims to deliver starter tennis to both adults and children, encouraging them to get active and play the sport.
Catherine will also use her time in Scotland to visit two of her patronages – Place2Be and The Art Room.
The busy royal mum will visit St Catherine’s Primary School to see how Place2Be’s work in Scotland, where she’ll observe how it is improving the emotional well-being of pupils, parents, families and school staff.
The visit will come off the back off her powerful work with the mental health charity Young Minds Matter, a new series exploring issues and work around the mental health of young children.
Promoting the charity through her editorship with the Huffington Post, Catherine penned a powerful essay, expressing her views on the matter.
“The mental health of our children must be seen as every bit as important as their physical health,” she began.
“For too long we have been embarrassed to admit when our children need emotional or psychiatric help, worried that the stigma associated with these problems would be detrimental to their futures.”
