Prince Charles and Princess Diana will be Ryan Murphy's next 'Feud'

If you think actresses are scary, wait until you see royalty.

Ryan Murphy's much-anticipated Feud hasn't even premiered yet, but the show is delicious enough that FX has already ordered Season 2 — and it will center around a relationship that still fascinates us to this day: The ill-fated marriage of Prince Charles and Princess Diana.

The couple's "wedding of the century" took place in 1981, but they separated in 1992 and were divorced in 1996, following years of apparent misery together and affairs on both sides. Diana died in a car crash in 1997 and Charles later married his mistress, Camilla Parker Bowles, in 2005.

Feud: Charles and Diana will consist of 10 episodes, set to premiere in 2018.

Super-producer Ryan Murphy and Jon Robin Baitz (Brothers and Sisters) will write and executive produce the second season. In addition to Feud, Murphy also oversees the hit anthology shows American Horror Story and American Crime Story for FX. Baitz is currently a consulting producer on the second American Crime Story season, Katrina.

Season 1 of Feud, centered around Bette Davis and Joan Crawford, premieres Sunday, March 5 at 10 p.m. on FX.
