Lizzie Cundy, 55, slips into a Union Jack flag dress and tiara as she gets ready for the coronation

Lizzie Cundy looked sensational as she donned a Union Jack flag dress for an Instagram snap on Saturday morning before King Charles’s coronation.

The British socialite, 55, looked ageless as she showed off her toned physique in Safiyaa’s form-fitting dress and sporting a glittering tiara.

The TV personality completed the patriotic ensemble in red stiletto heels — while raising a storm in her latest post.

She wrote excitedly, “Long live the king!! What a coronation! Let’s get the party started.. see you on @gbnewsonline at 4pm! It’s going to be a royal knee up! Long live the king ! #coronation.”

Lizzie showed off her gorgeous feature with a bronze makeup palette and a touch of pink blush on her cheeks, and finished off with a nude lipstick.

The stunner added a touch of bling with a dainty gold bracelet and rings.

Her highlighted dark brown locks were perfectly styled in waves as she wore it loose over her shoulders and back.

She sent fans into overdrive when one of them remarked, “Long live Princess Lizzie C.”

Another said, “Patriotic and glorious.”

“That dress is so cute, can I borrow it x,” another user wrote.

Earlier today, Lizzie took to her Instagram story and showed herself watching the coronation ceremony at Westminster Abbey from her TV.

She captioned it again: ‘Long live the king!!’

It comes after the TV personality took to her Instagram page on Thursday with a sweet throwback post in which she beamed with longtime boyfriend Michael Flatley while attending Eric Clapton’s restaurant gig.

Lizzie stunned in a red mini dress with a feather trim and a luxurious pink fur coat.

Showing off her incredible figure in the fitted number, she elevated her body with a pair of matching red heels.

The socialite took to Instagram as she wrote her post: “Reunited with my old friend @michealflatleyo258 #carls #birthday”

Meanwhile, Lord of The Dance icon Michael, 64, looked happy and healthy as he beamed to his longtime friend – three months after undergoing surgery for an ‘aggressive’ cancer.

The Irish-American dancer wore a chenille black shirt and matching trousers, along with white sneakers – as he posed for a photo with a big smile.

The creator of Riverdance appeared in high spirits – as one source revealed, he flew from Monaco, where he now lives.

The WAG was on hand at the celebrity-studded restaurant gig where Eric Clapton played for a six-figure sum, also featuring Ronan Keating and Gary Lineker.

The legendary guitarist, 78, who is rumored to join a slew of A-list stars on stage at the King’s Coronation this weekend, played a number of hits at the champagne-soaked soirée.

After making a hefty sum for the private gig, Eric played for Simon Cowell’s ex Jackie St Clair as she rang in for her husband Carl Michaelson’s birthday in style.

Speaking at the event, a source told MailOnline, “Eric performed for an hour at the bash, where champagne flowed all night.”

Jackie, 63, greeted guests looking sensational in a dark pink tiered dress with silver flecks sparkling in the light.

The former model elevated her height with a pair of sky-high platform heels and styled her dark brown locks into glamorous curls.

Carl looked sweet in a dark blue suit with a crisp white shirt and a pair of suede shoes.

Also in attendance were Gary Lineker, Ronan Keating and his wife Storm, all of whom posed for photos outside the venue.

Eric’s private appearance is at the basis of his rumored performance at the King’s coronation on Saturday.

There will be dancing all night long as Lionel Richie has been confirmed as one of the names taking center stage at the concert.

Take That, pop singer Katy Perry and world opera star Andrea Bocelli have also been signed up to appear at the event in the grounds of Windsor Castle, according to the BBC.

Other names revealed by the broadcaster yesterday include Welsh bass-baritone Sir Bryn Terfel and singer Freya Ridings who will perform a duet with producer and musician Alexis Ffrench.

Some 20,000 members of the public will attend the coronation concert on Sunday 7 May, which will be broadcast on BBC1 and Radio 2, along with catch-up services.

According to the BBC, the concert will “celebrate a new chapter in the country’s history” and will have “themes of love, respect and optimism” while celebrating the “four nations” and the Commonwealth.

It comes less than a year after Queen Elizabeth II’s platinum jubilee concert featuring music by Queen, Duran Duran and Diana Ross.

Lionel, whose hits include Hello and All Night Long, became The Prince’s Trust’s first global ambassador in 2019.

He said: ‘Sharing the stage with the other artists at the Coronation Concert is a once-in-a-lifetime event and it will be an honor and a celebration.’

The concert is accompanied by a 70-piece orchestra and a ‘house band’ consisting of the Massed Bands of the Household Division and the Countess of Wessex’s string orchestra.

There will also be the support of The Coronation Choir – a diverse group of performers including shanty singers, taxi drivers, farmers and reggae choirs.

Landmarks and locations across the UK will also be illuminated with lasers, drone displays and lighting.

Charlotte Moore, BBC chief content officer, said: ‘We have a world-class line-up of performers to look forward to for what promises to be a very special night of partying and entertainment.’
