That's So Lannister: Game of Thrones' Tommen And Myrcella Are Dating IRL

A Lannister always pays his debts... and dates his sister.

Dean-Charles Chapman, 17, and Nell Tiger Free, 15, are dating. You probably know them better by their characters' names on Game of Thrones: Tommen and Myrcella. Yes. Lannister siblings dating in real life.

(Disclaimer: We know the actors are not blood-related! This is just a bit of fun. Disclaimer No. 2: We know that their acknowledged Game of Thrones surname is Baratheon, but everyone knows they are really Lannisters by blood since they're the love children of twins Jaime and Cersei Lannister.)

The two haven't made any sort of official announcement -- they are teenagers, after all -- but they've left a social media trail that indicates they're up to things Tywin probably wouldn't approve of.

Here they are Saturday morning at a music festival:

Here's a little Twitter love letter:

And here's co-star Maisie Williams (Arya Stark) reacting:

("Bants" is short for "banter" -- like gossip or jokes or rumors.)

Well, at least they didn't push Bran out of the tent. Guess they aren't exactly like their parents!

Speaking of Maisie Williams, watch her attempt to break the Internet by taking a selfie with Harry Potter:
