After working together for five years and playing best friends on The Vampire Diaries, you’d think that Nina Dobrev and Kat Graham know each other backward and forward. However, that’s not always the case.

During a few rounds of The Newlywed Game with Entertainment Weekly, they surprisingly only knew a few major facts about one another, including Nina’s undying love for chocolate. (Notably, it was more hilarious when they didn’t know the right answers — especially when Kat realizes that Nina is obsessed with karaoking “I Like Big Butts” instead of Taylor Swift.)

But the real fun comes when they reveal their first celebrity crushes. For Nina, it was all about Leonardo DiCaprio, but she’s more into Bradley Cooper and Ryan Gosling now, while Kat guessed Jonathan Taylor Thomas.

Nina, however, didn’t really play the game when she gave her suggestion for Kat — she outed her hidden celeb crush! Kat is really into Jeff Goldblum, who comes up again in conversation when they talk about Jurassic Park, and Nina broke her gal pal’s trust when she revealed this secret intel.

“I can't believe she just left the cat out of the bag!” Kat exclaimed (and with that, it should be left the “Kat” out of the bag”). “It's not my first celebrity crush, that is my celebrity crush, and it's not supposed to be public!”

From there, they move on to a lighter topic: movies they love to quote on-set. When the conversation shifts back to Jeff, Kat exclaims, “I’m gonna kill her!”

After the interview was posted, the two continued their “fight” on Twitter. Nina linked to EW, tweeting, “This is my favorite Interview of all time. If I disappear or die in the next week - you'll know who kidnapped and killed me. @katgraham - because I publicly outed her deepest darkest secrets! Whoops!” Kat has yet to respond, so watch out, Nina!
