Lili Reinhart is Acknowledging KJ Apa's Birthday Today in the Best Way

It’s Riverdale star KJ Apa‘s 20th birthday today (happy birthday KJ!) and his co-star Lili Reinhart 1,000 percent wins the day with her hilarious well-wishes.

We already know these two are tight from the adorable pics they posted at the Wizard World Comic Con, but then again the entire cast seems super close.

Lili uploaded three videos (so far!) to Twitter to embarrass KJ.

“Happy birthday to the guy who always steals my phone and does sh-t like this. But I love you for it,” she writes on the first one, accompanied by a video of KJ making absurd faces.

In the second video, KJ is vigorously flossing his teeth and in the third he is making an honestly alarming Joker-esque face that is sort of impressive and sort of terrifying.
