Kelly Sawyer then keenly asked if the star in question was her co-star Josh, who played a young Prince Charles in the series.

She said: 'Was it Prince Charles? That's what we're all wondering. That's what we all want to know, was it Prince Charles?'

But Emma quickly ruled out the star despite their close friendship on set, adding: 'Actually no it wasn't Prince Charles, no, which was probably for the best because that was a long shoot so that could have been excruciating.'

Speaking out: It comes after Emma appeared to announce that she is 'queer' in an Instagram post shared last week 

The post came after it was announced Emma will star in LGBTQ+ drama My Policeman alongside Harry Styles.

Emma has kept tight-lipped on any talk surrounding her sexuality and dating life. 

Back in October, she was asked by Stella magazine if there was a 'boyfriend on the scene', and replied: 'I'd rather navigate this on my own. It's nicer to feel like I'm taking care of me.' 

MailOnline contacted Emma's representatives for comment at the time.

Emma is preparing to take on a role in My Policeman, where she plays a wife caught up in a polysexual love triangle. 

Set in Brighton in late 1957, the film, which is based on Bethan Roberts' novel, focuses on police officer Tom (Harry Styles), who is gay but chooses to marry schoolteacher Marion due to social expectations in the era.

Despite this, Tom embarks on an affair with Patrick (David Dawson) after the latter falls in love at first sight when they meet at Brighton Museum years later.

Marion becomes jealous when she discovers their passionate relationship, and decides to take drastic action during a time when homosexuality was illegal.

Rupert Everett will appear as the older version of Patrick in the film, while Harry will be replaced by Linus Roache. 

The 2012 novel explores the sexual mores of the 1950s and the criminalisation of homosexuality.

Emma soared into the spotlight last year with her breakout role as Princess Diana in Netflix's The Crown. 

The British star plays the late Royal in the fourth series of the drama, in a role which has won her widespread critical acclaim.
