Meghan posts clip of her dancing to a birthday song wearing tiara-like headband as Harry laughs

Meghan Markle has posted a new clip of her dancing to a happy birthday song wearing a tiara-like headband to celebrate turning 45.

The Duchess of Sussex posted a series of videos from her special day on Instagram, showing her bopping to the music and laughing as she and Prince Harry put paper hats on their two dogs, Pula and Mamma Mia.

In the new clips, Meghan shares a rare glimpse of herself in casual attire as she sports white pyjama bottoms and a T-shirt branded with the words ‘It’s giving Mrs’.

A birthday song plays in the background, while Prince Harry laughs and says ‘oh dear’ from behind the camera.

Her Instagram story then flicks to a second video showing the couple’s two dogs wearing paper hats – with the duke and duchess laughing as the pets appear less than impressed by their accessories.

The hats slip on and off the dogs, before Harry repeats ‘oh dear’ and Meghan chuckles, adding: ‘Oh no, okay, let’s take it off. I’m sorry.’

The clips came hours after Meghan marked the occasion by sharing photos of herself jumping into an outdoor pool while holding balloons – as she thanked her followers for ‘the birthday love’ on social media.

Her lifestyle brand As Ever also congratulated the mother-of-two with a snap of Meghan wearing a designer striped shirt from Céline and white Anine Bing ‘Brie’ jeans.

The company’s social media post also included a throwback photo of a young Meghan sporting pigtails and a white turtleneck, seated in what looks to be her childhood bedroom.

To mark the duchess’s birthday, the brand wrote on social media: ‘Happy birthday to our founder, @meghan. Lighting No. 084 to celebrate!’

The caption referenced a candle sold by the brand, which appeared alongside other As Ever products in one of a quartet of photos posted to celebrate Meghan’s special day.

Last weekend, Meghan showcased her jewellery collection during her latest promotional footage for As Ever.

On Sunday, she shared the recipe for her ‘favourite ice cream sundae’, made by placing her raspberry spread into a glass before adding vanilla ice cream, crumbled shortbread and flower sprinkles.

But royal fans couldn’t take their eyes off the former actress’ rings, which were on full display as she created the dessert.

She also wore a new, unidentified gold band on her right hand, and Princess Diana’s Cartier Tank Française watch, worth £17,800 ($24,020), which was given to her after she married the Duke of Sussex.

Meghan was also seen wearing her £2,370 ($3,197) Jennifer Meyer mini bezel tennis bracelet, which is handcrafted from polished 18-carat yellow gold and was designed by Tobey Maguire’s ex-wife.

However, despite the enviable jewellery collection on display, there was one item noticeably absent – the duchess’ £120,000 ($161,922) engagement ring.
