Pregnant Kate Middleton was all smiles as she joined her husband Prince William for a day of fun, riding in an off-road vehicle at Jaguar Land Rover's Solihull Manufacturing Plant this morning (22 November).

The 35-year-old Duchess of Cambridge – who is expecting her third child in April – looked impossibly chic in her recycled £680 white-trimmed black coat featuring gold buttons from Goat.

Dressing her burgeoning bump to perfection in the neat overcoat, she paired the look with black jeans and knee-high boots from Russell and Bromley. Kate was first spotted in the timeless coat back in 2014 during a trip to New York while she was pregnant with Princess Charlotte.

She completed the look with a £2,200 Kiki McDonough 18ct Yellow Gold and pave Diamond earrings and a small black clutch.

The duke and duchess were given an overview of JLR and the Sollilull site before heading over to the vehicle assembly area to view the assembly line and understand the manufacturing process by meeting staff and apprentices.

The royal couple, who looked to be in high spirits the whole time, later visited the Jaguar Land Rover Experience Centre, where they encountered Mountain and Cave Rescue volunteers taking part in a vehicle familiarisation exercise.

William is a key supporter of mountain rescue organisations around the UK, since he closely worked with them in Wales when he was a search and rescue pilot in the Royal Air Force.

The duchess appears to be over the worst of her acute morning sickness as she also drove a vehicle in the off-road driving area, impressing onlookers with her motoring skills.

She bravely overcame the windy elements in her wisely chosen outfit, with the coat believed to have had an extra panel added to the hemline to protect her modesty. Perhaps she was advised to do so by the Queen, whose favourite couturier Stuart Parvin sews curtain weights into her garments so that they don't blow up in gales.

William also had some fun behind the wheel of a Land Rover up a very rocky road, before chatting to some of the company's volunteers who back projects that focus on regeneration, education, young people and the environment.

The royal couple then attended Aston Villa's football ground – which is a treat for William since he has been a fan of the team since he was a young boy. There they saw the work of the Coach Core programme taking place in Birmingham.

The scheme works with Sport Birmingham to provide youngsters aged 16-25 the opportunity to become the next generation of coaches, offering them a chance to succeed in their careers.
