Zelo shared his birthday wish on Twitter, "Zelo, stop growing," and a snapshot of his frosting covered face. Now that he's getting older, it seems Zelo no longer wants to be known as his group's "giant baby" with his tall height of 184 cm (~6 ft.). Bang Yong Guk also took a candid photo of Zelo sleeping like the 'baby' that he is!

Youngjae replied to Zelo's birthday wish, "Ok Joo Nong. Please... keke I will eat the cake well, keke." Himchan also congratulated him, "Happy Birthday, baby."

BABYs also congratulated him, "Happy birthday, Zelo!", "Aw, sleeping with Yong Guk's tiger", and "Wish Zelo all the best on his birthday!"

Happy Birthday, Zelo!
