Their father Prince Charles will be at the shoot and Prince William’s son George may go along to catch the spectacle.
Harry, 34, has taken part in the family event for more than 20 years, but Meghan, 37, strongly opposes blood sports and refuses to wear fur.
Meghan’s aversion to hunting is believed to have first caused issues last year, when Harry reportedly took part in a wild boar hunt in Germany. Realising his then-girlfriend ‘wasn’t happy,’ he declined to join the Boxing Day hunt last year – before missing the grouse hunt at Balmoral three months ago.
Insiders say that Harry has changed hugely since meeting his American wife.
When the one-time ‘Party Prince’ took Meghan to Jamaica to celebrate the wedding of his best friend Tom Inskip, the couple were the first to leave the party and go to bed.
Since then, he has also become more distant from the group of friends he grew up with.
