Zara Tindall attends the Buckingham Palace concert with her husband Mike Tindall

Zara Tindall put on a stylish display as she joined husband Mike at the the Platinum Party in the Palace on Saturday.

The Queen’s granddaughter, 41, stepped out in a navy short sleeved number which she teamed with a black blazer as she sat behind the Cambridge’s at the star studded concert. She finished the look by styling her short blonde tresses in loose waves, and opting for a small pair of gold hoop earrings.

It has been a busy few days for Zara, following her appearance at Epsom Derby Day earlier today, Trooping the Colour on Thursday, and the Queen’s Service of Thanksgiving on Friday. But she didn’t appear to let her busy schedule dim her enthusiasm.

Zara, who seemed in high spirits as she joined in with the crowds raising her arms and waving a flag, was joined by her husband Mike, 43, who looked smart in a navy blazer and a pale blue shirt, which he wore casually with the top button open.

The pair were just two of the members of the Firm who attended the event, alongside senior royals including Prince Charles, 73, and the Duchess of Cornwall, 74, and Prince William, 39, and his wife Kate Middleton, 40, and their two oldest children Prince George, eight, and Princess Charlotte, seven.

The pair were seated directly behind Kate Middleton, 40, who is married to Zara Tindall’s cousin, Prince William 

Also spotted at the event were Princesses Beatrice and Eugenie, alongside their husbands Jack Brooksbank and Edoardo Mapelli Mozzi,  as well as Prince Edward and his wife Sophie, and their children Lady Louise Windsor and James Viscount Severn.

Kate Middleton, 40, dressed stylishly in a £400 Tailored Crepe Midi Dress from Self Portrait, worn with a white blazer.

She wore her brown locks styled in relaxed waves, swept over one shoulder, and finished the look with a delicate silver cross necklace and large ring earrings to match. 

The concert, which featured a packed programme including speeches by Prince Charles and Prince William, as well as performances by Diana Ross, Queen, and the cast of the musical Six, kicked off with a special short video clip starring Her Majesty. 

The Queen delighted millions of viewers by appearing in a surprise comic sketch with Paddington Bear to kick-start the Jubilee concert.

The monarch and the famous bear – both much loved British institutions – tapped out the beat of the We Will Rock You anthem together on china teacups using silver spoons as a unique way of getting the celebrations under way.

With the special, secretly-pre-recorded humorous two-and-a-half-minute sequence played at the start of the televised BBC’s Platinum Party at the Palace, the unlikely duo set the rhythm for opening act Queen + Adam Lambert – who joined in on the main stage.

Elizabeth II and the digitally animated character met for a chaotic cream tea at ‘Buckingham Palace’ in the footage, with the Queen revealing she shares Paddington’s love of marmalade sandwiches and keeps an emergency stash in her trademark handbag.

The duffle-coat wearing bear showed the Queen how he ensured he always had his favourite treat on him just in case, lifting up his red hat to reveal his snack.

The Queen responded by revealing ‘So do I’, before opening her bag and declaring: ‘I keep mine in here’, to show her very own ready-made supply of the bread and orange preserve staple.

Accident-prone Paddington was shown causing mayhem by accidentally depriving the understanding sovereign of another cup of tea and spraying cream from a chocolate eclair over a Palace Footman.

The bear from deepest darkest Peru congratulated the Queen on her reign of 70 years, saying: ‘Happy Jubilee Ma’am. And thank you. For everything.’

The modest Queen replied: ‘That’s very kind.’

It brought back memories of the Queen’s James Bond skit for the London 2012 Olympic opening ceremony, when the monarch met 007, played by Daniel Craig, and then appeared to parachute into the stadium, with the help of a body double.

Paddington and the Queen were pictured sitting opposite each other in ornate chair at a table, laid for afternoon tea, covered with a white linen cloth in an opulent room.

Buckingham Palace said the Queen felt the opportunity to invite Paddington to tea was ‘too fun to miss’.

The Palace said: ‘Her Majesty is well known for her sense of humour, so it should be no surprise that she decided to take part in tonight’s sketch.

‘There was an interest in the filming and animation process and the opportunity to invite a famous bear to tea was just too much fun to miss.

‘While The Queen may not be attending the concert in person, she was very keen that people understood how much it meant to her and that all those watching had a great time.’

The film was kept under wraps for several months by Buckingham Palace, BBC Studios and Heyday Films/StudioCanal.

Actor Ben Whishaw voice Paddington, just as he did in the hit movies of the children’s story.

Those involved in the film, which was actually shot at Windsor Castle, praised the Queen’s wit and warmth during the process, saying she shone and put them all at ease.

Mark Sidaway, executive producer for the BBC’s Platinum Party at the Palace said: ‘We were thrilled and honoured when we learned Her Majesty had agreed to run with this touching yet joyful idea the team had come up with – although it was slightly nerve-wracking ensuring it all blended seamlessly with the live performance from Queen + Adam Lambert.’

Rosie Alison of Heyday Films said: ‘Filming Her Majesty’s tea party with Paddington Bear was such an emotional day for the entire crew.

‘All of us were in awe of the Queen’s wit, warmth and radiant aura as she patiently engaged with a polite, clumsy but very well-intentioned bear.

‘Of course, she shone, and put Paddington (and all of us) at ease. Capturing this lovely encounter was an absolute joy and unique privilege for the whole team.’

Anna Marsh, chief executive of StudioCanal, added: ‘Filming with Her Majesty and Paddington Bear at The Palace is a memory we will all cherish.

‘Her Majesty’s warmth and generosity was a joy to behold. And who better to thank Her Majesty than Paddington, over a pot of tea, a marmalade sandwich, and with a touch of chaos. Aunt Lucy would be proud.’

Paddington, created by late British author Michael Bond, and the Queen share something in common – they both have two birthdays.

When Paddington was adopted by the Brown family, they agreed that bears, ‘just like the Queen’, have two birthdays every year.

The Queen’s actual birthday is on April 21, but she has an official one each year in June. Paddington’s birthday are – on June 25 and December 25.
