But she waited until after Meghan Markle's departure on Boxing Day to join her husband, Prince William, and other family members to blast pheasants, partridges and ducks on the Queen's 20,000-acre Norfolk estate on Thursday.
The Duchess reportedly used her own personal 20-bore shotgun for the shoot – the UK’s Mirror reported.
A source told the publication: "She frequently goes out shooting when she is staying at Anmer Hall and has become a really good shot."
Kate has been pictured previously with a shotgun – appearing totally at ease with the gun as she scoured the countryside.
The Duchess wraps up for the occasion - often wearing casual trousers and a body-warmer to keep out the chilly weather.
