Earlier this week, Clarence House released never-before-seen portraits of the royal family to mark Prince Charles' 70th birthday.
Now, royal fans have been treated to another two photographs from the shoot and Prince Louis certainly steals the spotlight.
Following in his older brother Prince George's footsteps, the six-month-old tot can be seen cheekily playing with his grandfather's face in the snap while the Duke and Duchess of Sussex lovingly look on.
In a surprising turn of events, Prince George and Princess Charlotte are unfazed by their little brother's behaviour and instead pose accordingly for the photograph, which was released this morning by the Sunday Times.
If that isn't enough to tug at the heartstrings, a second portrait depicts Prince Charles embracing his youngest grandchild while the six-month-old smiles on.
The images taken in the grounds of Clarence House were released to commemorate the heir to the throne's 70th birthday and were shot by royal photographer Chris Jackson.
For the group shot, the Duchess of Cambridge wore this year's most coveted £1,750 polka dot dress by London-based designer Alessandra Rich - an ensemble also worn by Suits actress Abigail Spencer and Pippa Middleton.
Meanwhile, the Duchess of Sussex stuck to her sartorial guns in a monochrome shift dress by Clare Waight Keller for Givenchy.
The nation has celebrated Prince Charles' birthday with a number of events this week from the ITV's star-studded We Are Most Amused and Amazed to a private Buckingham Palace dinner hosted by the Queen.
