If you've been glued to Netflix's "The Crown" I wouldn't blame you - I am too!
And they have just announced who will be cast as Lady Diana Spencer, who later became Princess Diana.
In a press release the streaming service announced Emma Corrin would be taking the role.
As for how Corrin feels about it?
She will be joining a stand-out cast including Oscar winner, Olivia Colman (who is taking over Claire Foy’s role as Queen Elizabeth II), Gillian Anderson (as Margaret Thatcher) and Helena Bonham Carter (as Princess Margaret).
The unfortunate part is that Emma's appearance will be made in Season 4, and we're yet to see Season 3. It is said Season 3 will be premiering sometime this year, so fingers crossed it's sooner rather than later!
