Helena Bonham Carter is reportedly the new Princess Margaret in 'The Crown' Season 3

Netflix's The Crown is about to get a new princess.

Months after Olivia Colman was crowned the new Queen Elizabeth II for Season 3, Variety reports Helena Bonham Carter has been tapped for the role of Princess Margaret.

The Evening Standard first broke the news.

The first two seasons of The Crown starred Claire Foy as Elizabeth II, Vanessa Kirby as Margaret, and Matt Smith as Prince Philip. However, showrunner Peter Morgan always planned to recast about every two seasons, to keep up with the characters as they aged.

Season 3 promises to be a big one for Margaret. Robert Lacey, the show's history consultant, has said that the next run of episodes will take place in the 1970s – which means that, among other things, it'll chronicle "the breakup of this extraordinary marriage between Margaret and Snowdon."

The Crown won't be Bonham Carter's first time joining the royal family onscreen. She previously played The Queen Mother – wife to George VI and mother to Elizabeth II and Margaret – in 2010's The King's Speech.

(Coincidentally, Colman has also played the Queen Mother, in 2012's Hyde Park on Hudson.)

Now all we need is a new Prince Philip and a release date for Season 3. Bring it on, Netflix.
