The INSIDER Summary:

• Kit Harington ran into former Spice Girl Geri Horner.
• She wanted to know how to properly say "You know nothing, Jon Snow."
• Harington tried to teach her, and it's adorable.
• Horner posted the video on Twitter.

"Game of Thrones" may be over, but that doesn't mean Kit Harington leaves Jon Snow completely behind.

While attending the Italian Grand Prix formula race in Monza, Italy, the 30-year-old ran into former Spice Girl Geri Horner (née Halliwell). 

The 45-year-old singer shared an adorable video on her Twitter of Harington giving her a lesson on how to say Ygritte's catchphrase associated with his character: "You know nothing, Jon Snow." 

Halliwell struggled to get the pronunciation of "nothing" right. She eventually nailed it, but then lost it again as the two laughed.
