WARNING: If you haven't watched this week's musical episode of Riverdale, leave now! For everyone else, it's time to discuss all those toe-tapping performances and jaw-dropping twists...

We're totally wigging out over all the surprise smooches in this week's episode of Riverdale.

In this year's musical episode, the hit CW drama treated fans to high-energy performances from Hedwig and the Angry Inch -- and we're pleased to say that Kevin Keller finally got his time to shine!

In preparation for Riverdale High's annual variety show, Kevin crowned himself with Hedwig's iconic blonde wig and officially cemented his place as one of the best performers in town. In celebration of this glittery achievement, ET called up 27-year-old actor Casey Cott to get the exclusive inside scoop on what it was really like to step into Hedwig's incredibly high heels.

Plus, Cott is revealing how that passionate kiss with KJ Apa came to be and what's coming next now that Betty and Archie's romance seems to have sparked back up again. 

ET: Congratulations on an amazing performance! What was your initial reaction when you discovered that this year's Riverdale musical would be Hedwig and the Angry Inch?

Casey Cott: I was pumped! I'd seen John Cameron Mitchell do it on Broadway and I'd seen the movie and when I found out that Stephen Trask, who wrote the music, was going to come, I was super excited. And I'm buddies with Darren Criss, who did it on Broadway, and his manager was actually visiting me in Vancouver when I found out we were going to do it. I was talking to her all about it and she was telling me stories and how she worked with Taye Diggs when he was doing it, so I was really excited. It was definitely the topic of conversation for a week for anyone within earshot of me.
