Meghan Markle posted a series of new videos from her family home in Montecito, California, showing her followers how she is celebrating her eighth wedding anniversary to Prince Harry. In the videos, Prince Harry can be seen carrying an elderflower cake and singing "Happy anniversary to mama and papa".

Prince Archie and Princess Lilibet can also be heard singing and cheering in the background. In another clip, Meghan can be seen blowing out the candles and giving her husband and kiss before the couple say " I love you to each other.

In yet another clip, Meghan can be heard squeaking while unveiling Harry's anniversary gift to her - two wooden penguins embracing.

She then explains to her children that when the two got engaged, they hosted a party with "all of their friends" in onesies and they went as penguins.

Prince Harry is dressed in blue joggers and a dark polo, while his wife is also in casual attire, consisting of a grey jumper and dark trousers.

She then adds to the camera: "We were penguins because we're together for life".

She also posted a picture of the two kissing in front of their anniversary cake, and another close-up of their penguin photo.

Later in the videos, the Duchess shows a close-up of her gift, along with the penguin picture, as well as a card presumed to be from her husband, which reads: "The one and only".

It's been a busy day for the Duchess, who has been marking her anniversary on social media since early morning.

At 8am UK time, Meghan posted 24 previously unseen photographs from her and Prince Harry's day to mark the occasion.

She also marked the day on her lifestyle brand, As Ever's, Instagram page by sharing a new photograph from their special day taken from above and advertising the 519 candle, which is inspired by the wedding.

The Duke and Duchess of Sussex married on May 19, 2018, in Windsor.
