In the most recent episode, titled 'Dundee', of the comedy-drama featuring Scotland's Brian Cox, the Edinburgh clubs are mentioned.
The show revolves around the dysfunctional Roy family who are battling for control of Waystar Royco - a global media and hospitality empire.
Cox, who plays the head of the family Logan Roy, features in the clip where he reveals himself as a Hibs fan.
However, he is surprised when one of his sons announces that he has bought his father Hearts.
Roman Roy tells his dad that he and a business associate have bought "the Hearts" as a present.
It surprises Logan who corrects his son and says: "I'm Hibs".
He then goes into an expletive-ridden rant: "How would I know what team I've supported all my ******* life."
It caught the attention of both Edinburgh clubs with Hearts tweeting their rivals: "Awkward".
Hibs stated: "We are all Hibs".
