Satu berita yang mengejutkan buat peminat setia kumpulan 2pm kerana ketua kumpulan tersebut telah pun meninggalkan 2pm dan pergi meninggalkan Korea. Ini adalah gara-gara kenyataan yang didakwa ditulis oleh JaeBeom di dalam lama myspace kepunyaannya yang menyatakan bahawa >Hal ini telah menimbulkan kemarahan penduduk Korea yang selama ini memuja kumpulan tersebut. Sedangkan ramai pihak mengatakan bahawa laman tersebut bukanlah kepunyaan ketuan kumpulan 2pm tersebut. Mengikut bacaan yang dibuat di dalam laman forum penyanyi kesukaan rama itu, perkara terkutuk tersebut dilakukan oleh anti 2pm yang ingin JaeBeom segera meninggalkan Korea. Motif perkara ini berlaku masih tidak diketahui kerana JYP Entertaiment masih tidak mengeluarkan sebarang kenyataan.
Bermula 8 Sept. 2009, secara rasminya JaeBeom telah keluar daripada 2pm. Ini berikutan surat yang diterima oleh JYPE iaitu >
Hello everyone this is 2PM’s Park Jaebum. I would like to apologize on behalf of the comments I had made through Myspace a few years ago. I’m sorry.
As I tell all of you about how I felt that time, I also would like to apologize. In January of 2005, I came to Korea as a high school student. I was born in the States and I had insufficient knowledge of how Korea is. Being it my first time, I couldn’t communicate with others, my taste buds didn’t fit, and I barely knew the culture which I couldn’t understand. I felt as though I was treated coldly by the people around me as my family was left in the States. It was such a difficult situation where I didn’t even know if I was going to debut. Due to many hardships, things were getting too hard and I was getting lonely being homesick. I had the thoughts of quitting and I wanted to go back to my family in the States. The comment based on the Korea part: I wrote that because of my personal situation I was placed in and my emotions took over. I was too young and said things in the wrong words. I was too foolish, young, and facing difficulties where I made the mistake into turning my surroundings worse. Time passed by and I forgot that I had even written them. I am now embarrassed and truly sorry of those comments I had made. After that time, I had adjusted to everything and my thoughts have changed tremendously as I thank the people around me to get me to perform on stage in any situation. Those comments were made four years ago, but I am a different person now. To my family, Hottests, members of 2PM, and those who love 2PM, I am truly sorry. From now on, I hope that there will be no mistakes like this ever again. I will say it one more time that I am truly sorry.
Ramai peminat yang kecewa akan hal ini telah membuat petisyen supaya JaeBeom tidak keluar terus dari 2pm. Tetapi, ia telah terlambat. Semasa di lapangan terbang, ramai peminat JaeBeom telah berkumpul untuk menghantar pulang JaeBeom ke Amerika Syarikat. Ramai di antara mereka yang tidak dapat menerima kenyataan dan bersedih akan kepergian JaeBeom.
