'Riverdale' Stars Lili Reinhart and KJ Apa Recreate '90210' Breakup Scene on 'WWHL' -- As Luke Perry Judges

Lili Reinhart and KJ Apa put their acting skills to the test Tuesday night by recreating an iconic scene from "90210," as original cast member Luke Perry watched and evaluated their performance.

While appearing on "Watch What Happens Live," the "Riverdale" stars were asked by host Andy Cohen to reenact Dylan and Brenda's break up from the '90s favorite as part of the show's segment "Clubhouse Playhouse." Cohen even had a green screen prepared for the actors, featuring a fake beach in the background.

"My guests may be fresh off Riverdale High's production of 'Carrie the Musical,' but I thought I would give them another theatrical opportunity, where hopefully this time no one gets murdered mid performance," Cohen said.

Cohen added that since Perry played Dylan in the original series, he could serve as "kind of an artistic director" to judge Apa and Reinhart's performance.

Although Reinhart and Apa weren't alive when the episode originally aired, they both nailed the scene. Reinhart embodied Brenda's absolutely ridiculous demeanor, while Apa played bad boy Dylan to a T.

For those that are unfamiliar with the particular break up moment from the '90s television drama, the scene from the Season 2 premiere showed Brenda (played by Shannen Doherty) breaking up with her boyfriend Dylan (Perry) after experiencing a recent pregnancy scare.

"I trusted you enough to have sex," Reinhart recited at one point and the audience busted into laughter. "Dylan, I do know what I'm feeling and I need to break up with you."

Although he looked a little uncomfortable during the reenactment, Perry ultimately gave his stamp of approval seeing his on-screen son play his role.

"That's good," Perry said adding a nod.

Joined by their co-star Madchen Amick, Reinhart, Apa, and Perry also participated in another segment on the late-night show called "River Heads," where the stars had to answer questions about the "Riverkids" -- Reinhart (Betty), Apa (Archie), Camila Mendes (Veronica), Cole Sprouse (Judghead), Madelaine Petsch (Cheryl) and Ashleigh Murray (Josie).

"Who is the biggest flirt behind-the-scenes of those people?" Cohen first asked.

While Apa and Reinhart both immediately said Mendes was the cast flirt, Amick put her arms on Apa's shoulders, pegging him as the culprit.

Cohen then asked who had the most people "sliding into their DMs." Both Apa and Reinhart named Sprouse as the one who receives the most messages.

"I don't know, you probably have a lot aye," Apa said to Reinhart, and she replied, "Not as much as Cole."

Cohen guessed that Apa must receive a lot of DMs as well and said that his Instagram inbox "must be going crazy."

"I mean it's not really something that I look at," Apa replied.

"It's just nudes constantly," Reihart joked.

The group also answered more questions about their costars, including who is the most likely to forget their lines and reveal a spoiler.
