Even after 15 years of marriage, the Princess of Wales can't help gazing at her husband with adoration.
During Tuesday's State Visit for the Sultan of Oman, Catherine and Prince William were offered a rare few minutes of privacy as they stood on the Royal Dais in Windsor.
As they chatted, the Princess couldn't hide her loving gaze and found it hard to keep her eyes away from William, despite the formality of the event.
Commenting on HELLO!'s Instagram post of the tender moment, one royal fan commented: "Her eyes are so pretty! She has the best aura."

"Such a loving couple, our future King and Queen," said another.
Catherine had arrived at the royal dais together with the King and Queen – a change to the usual arrangements because the Sultan wasn't accompanied by his wife during his stay.
She was then reunited with her husband, who had travelled separately to welcome the Sultan at his London residence.
Kate's loving glances at William
The royal couple have now been together for more than two decades, and they share three children: Prince George, 13, Princess Charlotte, 11, and Prince Louis, eight.
They first met when they were just 19 years old as students at the University of St Andrews in 2001, after both taking gap years. After starting as friends, they tied the knot in 2011 and celebrated 15 years of marriage this April.
Even now, when we see them in public, they still act as if they're the only ones in the room and can often be caught gazing wistfully at each other.

Some of their sweetest gazes over the year have been at Trooping the Colour – when the royals appear on the balcony for the monarch's official birthday.

Prince William and Catherine's busy week
Prince William and Catherine played a major role in this week's Omani state visit, in preparation for one day becoming King and Queen.
For example, the Prince of Wales stepped in for his father to greet the Sultan, and both were part of the ceremonial welcome and the evening's lavish banquet.
They've had a busy week of royal engagements as, on Wednesday, William joined King Charles and Queen Camilla for a poignant visit to Aberfan, to mark the 60th anniversary of the tragic mining accident.
Meanwhile, the Princess visited the Treehouse Hospice in Ipswich, East Anglia, on Thursday.
The unit provides short breaks and palliative support for children and young people with life-limiting conditions, and bereavement support for families.
The future queen, who opened the hospice in March 2012, saw its music therapy room and a sensory room with special lighting, a water bed and a projector.
On Friday, the couple's children broke up for half term, with Catherine revealing that she had missed son Prince George while he's been away at Eton College.
