A spokesperson for E! told Refinery29 of the cancelation:
"E! will not be moving forward with another season of The Royals, which launched in 2015 as the network’s first original scripted series. Over four seasons, The Royals took viewers behind the palace gates on a scandalous journey filled with twists and turns. We are grateful to the cast and our producing partners at Lionsgate and Universal Cable Productions."
In November of 2017, Schwahn came under fire after Audrey Wauchope, a writer on Schwahn's previous series One Tree Hill, tweeted about his bad behavior while working on the CW drama. After Wauchope's tweets went viral, crew members and stars on the series — including its women leads Bethany Joy Lenz, Sophia Bush and Hilarie Burton — published an open letter in Variety detailing allegations of harassment against Schwahn.
Until then: At least we can still count on E! to keep us updated with America's royal family, the Kardashians.
