Later in the episode, Veronica and Archie were singing "Mad World" at FP's Serpent retirement party, but the feuding couple left the stage before the song was over. In order to distract the restless crowd of Serpents, Betty grabbed the mic to finish the haunting ballad.
The so-called "girl next door" then seized her opportunity and treated the audience to an ultra-sexy strip tease and performed her Serpent dance up on a pole in black, lacy lingerie. Crazy, right? Oh, did we mention that Betty's mom, Alice, was also in the crowd. Awkward....
To get the inside scoop on Betty's strip down, Riverdale star Vanessa Morgan, who was on set during the scene, stopped by Sweetwater Secrets and dished on the shocking on-screen moment.
"I felt like I was watching a little strip show, but I felt for her too," Morgan revealed. "I think this was her moment where she was just showing Jughead like, 'I will do anything for you. I willl go extremely out of my comfort zone and I'll get down in lingerie and I'll do the traditional, female, sexist Serpent dance, [for you.]'"
"It was crazy watching it," she added. "It's one of those things where [as an actress] you're extremely out of your comfort zone, so kudos to [Lili Reinhart.] I watched the whole scene and I was like, 'Wow!' She got up there and she did it lots of times."
