"It rightly mocks poor behaviour by a tennis legend", Johnson tweeted.
Williams' heated exchanges with an umpire at the tournament final this week have stirred the tennis world.
She was then issued three code violations, which ultimately equaled $17,000 in fines.
"Well done on reducing one of the greatest sportswomen alive to racist and sexist tropes and turning a second great sportswoman into a faceless prop", said J.K. Rowling.

Australian cartoonist Paul Zanetti weighed in saying it was the job of cartoonists to call out bad behaviour and not fall prey to an increasingly politically correct culture.
