Emma Stone surprised the live audience on "Conan" when she expressed her "addictive" love for K-pop - and even name-dropped popular groups like 2NE1 and Girls' Generation. Watch her struggle to explain why she just can't get enough of K-pop, in the video below:

"It's like the combination - it's like - I don't know what it is - it's like - I don't even know how to describe it..." she stammered, finally stating: "It's all so addictive."

When host Conan O'Brien asked which K-pop group was Emma Stone's favorite, she said she was able to meet 2NE1 during the "The Amazing Spider-Man 2" premiere in Seoul, Korea. And it seems like CL, Minzy, Dara, and Park Bom stole her heart!

The minute Emma Stone mentioned 2NE1, the live audience erupted in cheers. Sounds like there's quite a few unexpected 2NE1 fans at "Conan"!

While Emma chooses to pronounce the group "two-anyone" instead of "twenty-one," as some others choose to call the group, the gorgeous red-headed actress corrected Andy Richter when he said all K-pop groups "have like, 15 members."

"Well, this one only has four," Emma Stone noted.

Emma also mentions Girls' Generation - which has eight members - and says it's another group "that I really enjoy," and the audience responded with another round of exhilarated applause.

Though Emma Stone admits to being "way behind the times" when it comes to K-pop, she did proclaim that 2NE1's viral hit "I Am The Best" is an "incredible" song.

The "Aloha" actress also added that the chairs in the "I Am The Best" music video are like the ones on "The Voice" - but "cooler."
