Jaime Lannister Just Let It Slip That Jon Snow Is Definitely A Targaryen

Hey, you know that Game of Thrones theory that's so popular it's pretty much just accepted as the blatant truth among fans of the show at this point? Yeah, that one about Jon Snow. Well, Jaime Lannister just totally confirmed it once and for all.

Nikolaj Coster-Waldau was caught a bit off guard by Jimmy Kimmel on Tuesday night. When the host poked fun at him for lying about Jon Snow's death before Season 6 on Jimmy Kimmel Live, Coster-Waldau attempted to defend himself by saying that Jon Snow is indeed still dead, and Jon Stark-Targaryen is in his place.

Jon Snow is dead, but Jon Stark-Targaryen has risen from the dead.

So yeah, I guess there's no question about it now! Coster-Waldau's statement confirms the widely accepted "R+L=J" fan theory that Jon Snow is part Stark and part Targaryen, as the son of Rhaegar Targaryen and Lyanna Stark.

The series has been teasing this reveal more and more in recent seasons, and many fans are anticipating that Season 7 (which premieres in just a couple of days) will finally reveal Jon Snow's Targaryen ancestry.

While Nikolaj Coster-Waldau was loose with the Jon Snow info on Jimmy Kimmel Live, Kit Harington laughed off questions about his character being a Targaryen one day earlier on the same show.

For hardcore fans of the series, Coster-Waldau's slip of the tongue isn't exactly game-changing news. It's been widely theorized for a while now that Jon Snow does, in fact, have Targaryen blood in him, making him even more of a formidable candidate for the Iron Throne.

It also means we might get to see Jon Snow riding into King's Landing on a dragon sometime in the near future, and maybe even teaming up with the only other remaining Targaryen, Daenerys!

Game of Thrones Season 7 will premiere on Sunday, July 16 at 9 p.m. ET on HBO.
