There had been speculation over how the brothers would be with each other as they came face-to-face for the first time since Prince Philip's funeral.
But the Queen showed no signs of concern as she visited the Edinburgh Climate Change Institute (ECCI) at The University of Edinburgh this morning, to learn about their work to combat climate change.
During the visit, she and Princess Anne - who has been Chancellor of the University of Edinburgh since 2011 - spoke to staff and students about their research into ways we can reverse the effects of climate change.
The mother and daughter also heard from academics about the newly-launched Edinburgh Earth Initiative, which will be a focal point for the University’s teaching and research on climate.
At the end of the visit, Her Majesty and Her Royal Highness met representatives from the Children’s Parliament who presented The Queen with two trees that will be planted as part of The Queen’s Green Canopy - a UK-wide tree planting initiative to celebrate Her Majesty’s Platinum Jubilee next year.
It marks the Queen's final engagement of this year’s Royal Week, which has seen Her Majesty undertake a range of engagements celebrating Scottish community, innovation and history.
Her Majesty was not among guests at the statue unveiling in Kensington Palace today.
Just 13 people joined Harry and William at the poignant event - including Diana's siblings Earl Spencer, Lady Sarah McCorquodale and Lady Jane Fellowes.
The brothers had been expected to put on a brave face for the event, but relations between them are said to remain frosty after Harry's bombshell Oprah interview.
The Duke of Sussex, 36, told Oprah in March that his relationship with his brother was one of "space" and claimed he and dad Charles are "trapped" in the Royal Family.
Harry has also dropped a string of sensational truth bombs on the Royal Family since the tell-all chat with Meghan Markle.
It means the brothers will have plenty to get off their chests when they reportedly join Kate Middleton for a heart to heart at Kensington Palace later.
