Meghan and Kate stroll side-by-side to church as thrilled crowds are treated to the first glimpse of the pair together

Meghan Markle has become the first fiancee to join the Royal Family at Sandringham for Christmas - and marked the occasion by playfully sticking out her tongue in front of adoring crowds and performing a curtsy for The Queen.

The Suits actress stepped out in a wide collar camel wrap coat, made by Canadian luxury brand Sentaler, which tapered in around the waist and flared out at the hem, for the St Mary Magdalene Church Christmas service.

Matching her camel coat with a chestnut-brown felt hat, Meghan wore a pair of coordinating £630 Stuart Weitzman's Hiline high-heeled suede boots.

Meghan, 36, clutched on to her Royal beau Prince Harry and proudly displayed the engagement ring that he designed before their engagement in November.

She seemed at ease as they smiled and chatted during the short walk to St Mary Magdalene Church alongside William and Kate, who is pregnant with her third child and showed off a small baby bump beneath a striking £2,655 tartan Miu Miu coat.

It is the first time the two women have been pictured together since Meghan and Prince Harry revealed their impending nuptials.

The Queen arrived at the service later by car wearing an eye-popping orange jacket with a matching intricate floral hat.
