SEE ALSO: Fans wish MBLAQ's Lee Joon a happy birthday on Twitter

A few photos from his sudden party were revealed on Naver's 'StarCast' segment along with two clips from the day. 

Although it seemed like the MBLAQ members and Pro C had done a good job of surprising Lee Joon, the video clip shows a message at the end that reads, "The most surprising twist since the movie 'Sixth Sense', Lee Joon had been acting surprised. He had found out from a spy within MBLAQ that there was a surprise event in store". Nevertheless, he seemed to be genuinely touched by the gesture, and the event seemed to brighten up the tired members as they wrapped up a magazine photoshoot.

Lee Joon also shared in a second video clip, "Hello! It's Lee Joon. It's my birthday. Honestly, I've never thought of a birthday as a special day. But because my Pro C friends, MBLAQ members, many staff, and awesome fans congratulated me, I think of it gratefully. When it's your birthday, I want to congratulate you as well. So if it's your birthday, please tell me. Even though I can't do a lot, I can at least pay for a cup of coffee. I want to do everything possible. I don't need any presents. Eat a lot of delicious food, work hard, be healthy, and it's the start of the year so don't get hurt. The flu is spreading these days so I hope to keep living healthily. I have no future plans. I am playing right now. And in the future, playing with you all is my goal. Let's play together soon! See you soon."

Happy birthday once again to Lee Joon!
