Claire Foy is returning to The Crown for Season 4 (Report)

Claire Foy is returning to The Crown for season four.

Metro report that the actress was recently spotted back on set, filming what appeared to be a flashback sequence from the queen's 21st birthday.

The 35-year-old was spotted filming scenes dressed similar to how the Queen was dressed: wearing a white dress and a string of pearls.

She was also seen speaking into a microphone with a BBC sign attached, like the queen used during the broadcast.

It comes as Netflix recently responded to the reports that Imelda Staunton is set to take over the role of Queen Elizabeth II for seasons five and six of the royal drama.

However, a spokesperson for the streaming service told DigitalSpy that the reports were "pure speculation".

“We are currently filming season four of The Crown, but have not commissioned any further seasons as yet," they said.

The third season arrived on Netflix earlier this month.

The new season sees a new guard sweep into Downing Street, as Queen Elizabeth and her family struggle to meet the challenges of a rapidly changing Britain.

From cold-war paranoia, through to the jet-set and the space age - the exuberance of the 1960s and the long hangover of the 1970s - Elizabeth and the Royals must adapt to a new, more liberated, but also more turbulent world.

And with the new season comes a number of big casting changes, as well.

Olivia Colman and Tobias Menzies have been confirmed to be taking over the roles of Queen Elizabeth and Prince Phillip from Claire Foy and Matt Smith.

Meanwhile, Helena Bonham Carter will be stepping into the role of Princess Margaret, which was previously played by Vanessa Kirby.

Josh O'Connor has also been confirmed to be playing Prince Charles, while Princess Anne will be played by Erin Doherty.
