The Crown season 6 premiere: Princess Diana actress Elizabeth Debicki is chic in black dress as she's joined by on-screen sons Rufus Kampa and Fflyn Edwards at LA screening

Elizabeth Debicki was joined by her on-screen sons, Rufus Kampa and Fflyn Edwards, at the Los Angeles premiere of The Crown, season 6.

The Australian actress, 33 — who plays Princess Diana in the new season — looked chic in an off-shoulder Bottega Veneta black dress at the event, held at the Westwood Regency Village Theatre on Sunday.

The blonde beauty paired the ensemble with pointed-toe black Manolo Blahnik heels and sheer black Calzedonia stockings.

Her golden tresses were parted in the middle and styled straight. As for glam, she opted for a delicate glow. 

While on the red carpet she happily posed with Rufus, 17, and Fflyn, 14, who star as the younger versions of Prince William and Prince Harry. 

Both of the boys looked dapper in matching black tuxedos and bowties. 

Elizabeth also posed with Khalid Abdalla, 42, who plays Princess Diana's romantic partner, Dodi Fayed - Egyptian film producer and son of billionaire Mohamed Al-Fayed. 

Princess Diana and Dodi tragically died in a car crash in Paris on August 31, 1997. 

The actor looked handsome in a black suit with a white shirt underneath.

At one point he raised his hand to reveal a message. He had the words 'ceasefire now' written in a black marker on his palm, in regards to the Israel-Palestine conflict.

Meg Bellamy and Ed McVey — who star Kate Middleton and a grown up Prince William — made a stylish duo on the red carpet.

Meg wowed in a plunging silk black Stella McCartney gown with a rhinestone trim.

She wore her chocolate-toned hair in a straight style and accentuated her pout with red lipstick.

Ed looked sharp in a white shirt with black embellishments, and sleek black pants. 

Ed and Meg also posed with Luther Ford, who plays an older Prince Harry. He showed off his biceps in a sleeveless black silk top, which he paired with black pants. 

Jonathan Pryce, 76, looked dashing as ever in a sharp grey suit. The actor plays the late Prince Philip, Duke of Edinburgh in the series.

He was pictured joking around with a King's Guard actor, as he tried to get him to break character. The King's Guard has strict rules to abide by, including not speaking or smiling while on duty. 

Ava Michelle, 21, was also present, and looked incredible in a pastel pink pantsuit. She wore her tresses parted in the middle and slicked back in a bun.

Suzanne Mackie, 38, wore a vibrant sparkling aquamarine dress with silver heels. 

CEO of Netflix Ted Sarandos, 59, looked sharp in a black suit.

Rufus Wainwright, 50, was joined by his daughter Viva Katherine Wainwright Cohen.

He was also joined by partner Jorn Weisbrodt, with both rocking scarves, blazers and jeans. 

Madeleine Byrne rocked a grey vest and pleated mini skirt to the event.

Maddie White cut a glamorous figure in a black and white gown paired with a pearl necklace.

Julia Kelly put on a leggy display in a short black blazer dress.

The show's creator Peter Morgan, 60, was handsome in a grey suit. 

In October, a first glimpse of images from season six revealed how the Netflix series is set to recreate some standout royal moments from history.

And, according to the snaps released by the streaming giant, fans will see some historic moments recreated on screen - including Princess Diana's final days before she died in a car crash in Paris in August 1997.

A statement by the streaming giant revealed that the season will cover the time period around the death of Diana, Princess of Wales, as well as covering the meeting of Prince William and Kate Middleton in the early 2000s. 

It says: 'A relationship blossoms between Princess Diana and Dodi Fayed before a fateful car journey has devastating consequences.

'Prince William tries to integrate back into life at Eton in the wake of his mother’s death as the monarchy has to ride the wave of public opinion.

'As she reaches her Golden Jubilee, the Queen reflects on the future of the monarchy with the marriage of Charles and Camilla and the beginnings of a new Royal fairytale in William and Kate.'

Among the iconic royal moments set to be recreated in series six are Prince Harry and Prince William's summer trip to Balmoral in August 1997, which is where they received the news their mother had passed away.

Season six of the series picks up where season five left off, with Prince Charles and Diana, Princess of Wales, spending Summer apart for the first time as a now-divorced couple.

The two parents are seen having two very different holidays with their sons Prince William and Prince Harry.

According to executive producer Suzanne Mackie: 'We're very much in the beginning of the Princess Diana and Dodi Fayed story.

'From the second she steps onto that boat and [you begin to see] some of those iconic images of her on the yacht, it does take you immediately to the whirlwind that was the press speculation around that romance.'

Netflix recently released a first trailer for the upcoming series, showing Imelda Staunton returning as Queen Elizabeth. 

It also featured snippets of footage of previous Queen actresses Claire Foy and Olivia Colman in a nod to the series' decades-spanning journey.

'The crown is a symbol of permeance. It's something you are, not what you do,' Foy said, as a television flickered footage of her in character to begin the trailer.

She first starred as the monarch in seasons one and two of The Crown, and played a young Queen Elizabeth.

'Some portion of our natural selves is always lost. We have all made sacrifices. It is not a choice. It is a duty,' Colman then echoed.

The video rolled to a framed photo of her in character as the sovereign, who she played in seasons three and four

The clip dramatically then cut to Staunton in costume, quietly holding her hands before stepping out onto a Buckingham Palace-like balcony to greet a cheering crowd.

'But what about the life, I put aside? The wouldn't — I put aside?' Staunton's voice then questioned.

It was previously thought that the drama would run for five seasons, but then creator Peter Morgan decided to go back to his original plan of having six installments of the show.

He told Deadline: 'As we started to discuss the storylines for Series 5, it soon became clear that in order to do justice to the richness and complexity of the story we should go back to the original plan and do six seasons.

'To be clear, Series 6 will not bring us any closer to present-day it will simply enable us to cover the same period in greater detail.'

The final installment of the royal drama will air in two parts, with the first half of the series dropping on Netflix on November 16, with four episodes, and the second on December 14, with the final six episodes.
