Prince Harry kisses Meghan as he makes cameo in her Netflix Christmas special

Prince Harry has made a return to his wife's cooking and lifestyle show for the first time since its premiere in March.

The first trailer for Meghan's festive-themed Netflix special was released on Thursday morning, showing the Duchess of Sussex "embracing traditions and making new ones".

Prince Archie, six, and Princess Lilibet, four, make an appearance, of sorts, as their mother shares a letter they have written to Santa.

Watch the video above.

The one-minute clip begins with the song Jingle Bells and shows Meghan skipping through a Christmas tree farm, making cocktails and kissing Prince Harry in the kitchen.

"I love the holiday season," Meghan says.

"It's about finding time to connect with the people we love."

The Duke of Sussex made a brief cameo at the end of season one, which aired in March, but was absent from the second.

It's not clear how much of Prince Harry viewers will see in the one-off, Christmas-themed episode, titled With Love, Meghan: Holiday Celebration.

"Being a hostess or a host, it's about making people feel comfortable," the duchess says.

"You can do things that make people feel a little bit more seen," hospitality expert Will Guidara tells her.

Other guests who will appear throughout the show include tennis player Naomi Osaka, chef Tom Colicchio and the duchess' friends Kelly McKee Zajfen and Lindsay Jill Roth.

They are seen doing craft and making homemade wreaths, Advent calendars and icing biscuits.

The short preview also included a letter to Santa from Prince Harry and Meghan's two children.

It was written onto a white ceramic mug in Meghan's calligraphy and while the whole text can't be seen, the words "have been good" and "travel safely" were spotted.

The Santa note was signed "XO, Archie and Lili".

The show will be available through Netflix on December 3.

"Let the festivities commence and embrace the special touches that bring you joy," Meghan says.

The festive edition was first announced by the streaming platform in August, following two regular seasons.

However, there's been no confirmation of a third series.

Yesterday, the duchess emailed subscribers of her accompanying lifestyle brand As ever promoting its latest festive-themed product, sage honey, with a recipe ahead of Thanksgiving.

"When it comes to our founder's favourites, the delicate, herbaceous flavour of sage ranks high on the list," the email said.

"Why, you ask? Well, those photos you've seen this year on our Instagram of Meghan walking through what seems like lavender, with its gorgeous purple hue, actually share the beauty of flowering sage.

"Those strolls, with Archie and Lili running in tow, her husband checking on the bees, Pula chasing the ball with Mia trying to keep up – those were the sun-drenched moments that made an everyday walk something a bit more magical.

"And that sage, that purple, that scent around the garden, was always there in the background.

"And so begins our Montecito Thanksgiving love story. When dreaming up the Holiday Collection months ago, Meghan imagined what it would taste like to have a sage honey drizzled on her Thanksgiving turkey.

"And tah-dah! Here we are: a stunning sage honey, aromatic and earthy, epicurean in its depth of flavour and elegant simplicity, inspired by the treats she enjoys at her home with her family."

In late October, the duchess launched a range of new 'holiday' themed products through As ever.

A $97 scented candle – No. 0519 – was inspired by "the ease and joy of a day that holds Meghan's most cherished memories – her wedding day".

Other new additions to the holiday collection include a spiced cider mulling spice kit and hot toddy mulling spice kit (both $25), sage-flavoured honey ($49), and a three-pack of 'signature fruit spread' in a gift box for $64.

A new sparkling wine has also been released.
