An old photo of Big Bang members Taeyang and G-Dragon is causing quite the stir online.

The two Big Bang members are the same age, being born in 1988 and are known to be old friends who trained under YG Entertainment together since they were young. To celebrate the 'Year of the Dragon' Lunar New Year, Taeyang shared the above photo on his Twitter page saying, "Double Dragon."

Different from the charismatic way they carry themselves on stage today, both boys looked like adorable innocent rascals grinning ear to ear.

Netizens who came across the photos responded with, "Both are so cute", "They grew up so well", and "It's good to see they still have a close relationship".

In related news, the Big Bang members released teaser images on the 21st for their highly anticipated comeback.
