Lili Reinhart Says KJ Apa Is Superhuman, Runs 'Extraordinarily Fast'

If you saw last week’s episode of Riverdale, then you may have seen Lili Reinhart and KJ Apa running pretty fast.

The 21-year-old actress dished on filming the scene with her co-star and how she was shocked at herself.

“I was surprised by my stamina and how much I was able to run. But then you see K.J. rocketing past me!” Lili told Glamour.

“K.J. is a superhuman. He can run really fast,” she added. “And I can run really fast�and I was running really fast�but then compared to K.J. I look like I’m going pretty slowly and am a wimp. K.J. is just extraordinarily fast. I’m not slow. So I want that on the record!”
