Fans have been given a glimpse of Helena Bonham Carter as Princess Margaret in season three of the Netflix series The Crown.
She's taking over from Vanessa Kirby who played the Queen's sister in the first two seasons.
The director, Peter Morgan, has decided to change all the actors every couple of series as the characters age throughout the Queen's life.
The streaming service also released a photo of Ben Daniels, who will play the Princess' husband, Anthony Armstrong Jones.
Daniels replaces Matthew Goode.
Earlier this week, fans got a chance to see Olivia Coleman in the lead role, as she replaces Claire Foy.
The first two seasons portrayed the early years of the Queen's reign from 1956 to 1963.
The new series will air on Netflix in 2019.
We can't wait for it to be released.
