KJ Apa and Miley Cyrus face-off on Jimmy Fallon

The cast of Riverdale faced off with the Cyrus family on The Tonight Show Starring Jimmy Fallon last night!

It was for a game of 'Search Party' where they had to race to fill in the blank for random Internet search results for queries like “Should I Pierce My…”

Riverdale‘s KJ Apa, Lili Reinhart, Camila Mendes, Cole Sprouse and Madelaine Petsch went head-to-head with Miley, her sisters Noah and Brandi and their mum Tish.

Our Kiwi lad KJ was met by Miley Cyrus on-stage for a very important and burning question... "Should I Milk My...?"

Watch the video above! Miley and KJ are at 3.44s.

The Riverdale cast also talked to Jimmy about the upcoming second season, which debuts on Wednesday (October 11):
