Bridegerton is nominated for twelve Emmy Awards following the first series - which was released on Netflix on Christmas Day - being a huge hit.
The bash is set to take place on Sunday in Los Angeles with the biggest names in U.S. prime time television programming coming together to walk the red carpet.
However, the cast of the series have reportedly been 'prohibited' from going across the pond to rub shoulders with A-listers due to fears of them being at risk of catching covid - which would lead to the production of the Regency-era drama being brought to a halt.
"Publicly the stars are putting on a brave face and the corporate line is that they are happy to watch from home," an insider told The Sun.
"However, there is huge disappointment and upset, because many of them wanted to head over to Hollywood to celebrate all they have achieved.
"People forget that the cast never had a chance to do premieres, media appearances or meet and greets because of the restrictions.
"When the Emmy noms came through the feeling was that there would be time made for them to head to LA to truly celebrate."
Shedding light on other issues, such as visas, the source added: "But Covid outbreaks mean the show is running behind and there are immigration issues around some talent wanting to fly in but needing the correct visas."
The Mirror has contacted a representative for Netflix for comment.
It comes as no surprise that Netflix bosses being super cautious about the cast as British-based Bridgerton has been forced to halt production several times amid the pandemic.
Reports claim that production was halted twice in July and for a third time this month.
One Bridgerton star who is expected to attend the 73rd Primetime Emmy Awards is Regé-Jean Page - as the actor, who rose to fame as Simon Bassett, Duke of Hastings - is not part of the series two cast.
The actor - who broke fans' hearts by announcing that he was only taking part in season one - may be pleased to hear that there is no chance of him bumping into his old colleagues as he recently revealed that he is no longer in a group WhatsApp chat with his former co-stars.
The star told that he "respectfully exited" the group chat as he did not want to be 'kicked out' as he is no longer on the cast.
When asked by GQ if he was still in the chat, he said: "No, the universe has expanded. So I’m no longer in it."
The heartthrob added that he was not booted out, as he went on: "No, I respectfully exited. I didn’t want to put them in an awkward situation where they had to kick me out."
