Crowds started gathering at Buckingham Palace from around 7 in the morning and it was well worth the wait with Trooping the Colour well and truly delivering the very best of British Royal pagentary.
The celebration, which is the official marking of Her Majesty, Queen Elizabeth's birthday, sees the entire family gather and culminate on the palace balcony.
Taking a step out of the Centre room in the castle, fans got a glimpse of Duchess Kate, Prince Harry and newest royal Meghan Markle - who all took a moment to wave at fans on the balcony as they await for the Queen's arrival.

The best moment from Trooping the Colour goes to Prince George and Savannah Phillips
It's official: The Queen's great-grandchildren just stole the show!
Princess Charlotte looking away as her cousin Savannah Phillips teases Prince George actually has us LOLing.
It looks like she's trying to stop George from belting out some very cute vocals.
Watch: See that moment in the video player underneath!
Prince George and Princess Charlotte's outfit
Charlotte matched with her mummy, also wearing baby blue.
It hasn't been confirmed but the print does look like something that could have been designed by an old school friend of Catherine's, Alice Avenel.
Her pal from Marlborough college created Charlotte's Periwinkle dress under her brand Little Alice London, which she wore when she met Prince Louis.
See some of the times she's worn the designer below!
Prince George was darling in his white shirt by British childrenswear brand Amaia with navy blue piping.
We saw him in the shirt back in 2016 for Trooping the colour.
Who had the most fun? Meghan or Charlotte?
The British Royal Family can't wait for the RAF fly past
We've seen Queen Elizabeth, Duchess Kate, new royal Duchess Meghan with husband Prince Harry along with the rest of the British Royal family including Duchess Camilla and Lady Louise all ride past in horse drawn carriages.
The iconic Brits are awaiting in Buckingham Palace before they can go out onto the balcony to greet fans and watch the RAF fly past.
And judging by these snaps - they can't wait to see the iconic procession, taking a quick look outside the palace windows.
Duchess Catherine & Duchess Camilla
Looking beautiful in pale pastels, Duchess Catherine and Duchess Camilla were the first of the royals to make their way to the Palace.
Both women opted to wear pale blue hues, which complimented the birthday girl's pretty bright blue outfit.
Catherine, who welcomed Prince Louis just two months ago, went with one of her favourite designers - a pastel blue dress created by Alexander McQueen, teamed with a matching hat by Juliette Botterill.
Camilla opted for a blue Bruce Oldfield coat and dress.
And right behind them were newlyweds the Duke and Duchess of Sussex!
Unsurprisingly Meghan, who is often compared to her sister-in-law, went for a completely different look.
The Duke and Duchess of Sussex
Prince Harry and Meghan Markle look very in love as they rode in.
The newly minted royal, Meghan, decided to also stick to the pastel theme, donning for pink hues - her choice for her very first royal appearance after she married Harry.
The Duchess wore a pale pink off-the-shoulder dress by Carolina Herrera with a matching hat by Philip Treacy.
Harry wore his ceremony uniform of the Blues and Royals.
Fans were ecstatic to see the couple - screaming with joy as they got a glimpse of the pair.

Her Majesty looks resplendent in a bright sky blue outfit designed by Stuart Parvin.
The birthday girl, who was actually born on April 21 but marks her milestone officially in June, teamed her outfit with the prettiest matching blue hat that featured a floral arrangement.
The accessory was created by Her Masjesty's go-to millinery creator Angela Kelly.
Riding alone seemed to be no problem for the Queen, with her husband Prince Philip deciding to skip the event now that he's retired.
The Queen's loved ones
Prince Philip may have opted to skip the event for his third time, but the Queen wasn't short of loved ones.
Taking charge, we saw Princess Anne and Prince Andrew ride on horse-back.
While the Duke of York's daughter Beatrice and Eugenie were in a carriage with Sophie of Wessex and her daughter Lady Louise.
What pageantry! Meet the guards who are saluting their queen
The annual event will see more than 1,000 soldiers taking part in the traditional display of pomp and pageantry.
The colour being paraded this year is the flag of the 1st Battalion Coldstream Guards.
Some of the Queen's guards began preparing for this big moment back in April.
It's clear the Queen is sending a message of diversity, with 22-year-old Guardsman Charanpreet Singh Lall being the first Coldstream Guards soldier to wear a turban.
The 22-year-old couldn't be prouder, saying it is a "new change in history".
