Korea’s little sister, IU sure is one popular artist. And at such a young age, she may be making millions! Almost 4 million, actually. She is said to have earned 300 million won total, which is $261,600 USD, from her duets with 2AM’s Seulong in the song Nagging, It’s You with Sung Si Kyung, and from her third mini album Real. And that’s just in music. Looking at all the CFs she did, she probably earned around 1.4 billion won (1.22 million USD). And then there are variety shows, especially SBS’s Heroes. Adding all her show appearances, she probably earned around 500 million won ($436,000). So adding all that up, she probably has earned around 4 million USD. That’s one huuge moneymaker right there! It’s not that surprising, seeing how much her popularity has grown this year!
