The Duchess of Cambridge and the Queen embarked on their first joint royal engagement this week, visiting King's College London.
While the pair have been to many events together in the past, this was the first time it was just the two of them - the opening of Bush House, the latest education and learning facilities on King's College's Stand Campus.
Kate and Queen Elizabeth were spotted arriving at the university sharing a blanket on their laps inside the car. The pair sat next to each other, looking cosy and all smiles upon arrival - a very sweet bonding moment between the granddaughter and grandmother-in-law. The royals are often known to travel with a blanket on their laps, with Kate and the Queen both being spotted with the blue blanket on previous trips.
The royal duo toured the facilities and met supporters of the development, with the Queen unveiling a plaque to formally open Bush House.
Kate has always been fond of her grandmother-in-law, even giving her daughter Charlotte the middle name of Elizabeth. She has also spoken highly of Her Majesty in interviews, such as when she wasn't sure what to get the Queen for Christmas:
"She really cares. I can remember being at Sandringham, for the first time, at Christmas. And I was worried what to give the Queen as her Christmas present. I was thinking, 'Gosh, what should I give her?' I thought back to what I would give my own grandparents. And I thought, 'I'll make her something.' Which could have gone horribly wrong. But I decided to make my granny's recipe of chutney. I was slightly worried about it, but I noticed the next day that it was on the table. I think such a simple gesture went such a long way for me and I've noticed since she's done that on lots of occasions and I think it just shows her thoughtfulness, really, and her care in looking after everybody."
