Hey, Kourtney Kardashian – join the klub.

In a “Know Thy Sister” video – essentially the Newlywed Game – with Khloé Kardashian posted to her app/website Monday, the reality star reveals that her childhood crush was none other than Hollywood heartthrob and Oscar golden boy Leonardo DiCaprio, who finally won for The Revenant on Sunday night after netting five nominations in his career.

Khloé, 31, must have missed his swoon-worthy performance in Titanic, because she guessed Kourtney, 36, would pick Beverly Hills, 90210‘s Luke Perry.

“Yeah right!” Khloé cried after losing the round. “He’s, like, younger than you.”

“I used to write my name like Kourtney DiCaprio in class,” the mom of three confessed.

Sorry, Kourt: DiCaprio, 41, may also be single after splitting from his latest model girlfriend, Kelly Rohrbach, in January, but his heart belongs to his Academy Awards date: mom Irmelin Indenbirken.

“I’m so happy and I’m so proud of him,” she told PEOPLE backstage Sunday after her son used his acceptance speech to advocate for environmentalism. “And even more I’m so proud of his speech, that he spoke about something so personal to him and that with his platform, the whole world will listen.”
