Prince Louis of Wales attended a royal engagement with his parents on Friday and we can't believe how grown up he looks!
The five-year-old son of the Prince and Princess of Wales joined his parents and siblings, Prince George and Princess Charlotte, for a trip to the Royal International Air Tattoo in Fairford where the children were treated to a day of jets, helicopters and historic planes.
Dressed in a smart navy jumper, white shirt and navy chino shorts, Louis looked to be taking the event seriously as he and his family met senior members of the RAF.
In one photo, Louis is pictured waving – the cutest royal wave – as he sits on a vehicle on a C17 plane, which was surely an exciting occasion for the youngster.
The C17 aircraft has links to the royal family as it was used to transport the late Queen’s coffin in the days ahead of her funeral last September.

Louis also walked independently from his parents instead of holding their hands – another sign of his increasing maturity.
The royal will be going into Year 1 at school in September after completing his first year at the prestigious Berkshire school, Lambrook, near to his family home in Windsor.

William and Kate brought George to the air show just before his third birthday in 2016, with the youngster donning ear defenders. However, none of the Wales children were pictured in ear defenders on Friday.

The Prince and Princess of Wales have a strong relationship with the RAF, with the Prince having served with the Search and Rescue Force for over three years, based at RAF Valley in Anglesey.
The Prince is Honorary Air Commodore of RAF Coningsby and The Princess is Honorary Air Commodore of the Air Cadets.
