With JYJ's Yoochun celebrating his 27th birthday today, fellow members Jaejoong and Junsu took to Twitter to publicly send the birthday boy their own greetings & messages for the occasion.

Instead of announcing the big day himself, Yoochun decided to tweet his 'Rooftop Prince' co-star, Kim Sohyun, greeting, "Happy birthday to you~^^ The fact that we have the same birthday~ somewhat~ makes it better~ Congratulations^^" to which the young actress sincerely thanked him.

Yoochun continued to tweet, remarking, "I was lying down preparing to sleep~ and then messages started pouring in so I was startled^^ Thank you everybody so much~!!!^^"

In response, Junsu tweeted, "Yoochun-ah happy birthday!!!" To fans' delight, Jaejoong took it a step further, posting old photos of Yoochun getting his face caked.

"This was last year~^^," Jaejoong tweeted with the photos below. "Aigoo my stomach~ke" Poor Yoochun!
