Back on December 3-4, SHINee's Jonghyun held his 2nd ever solo concert, 'JONGHYUN - X - INSPIRATION', at the Hwa Jung gymnasium inside Seoul's Goryeo University.

During one showing, fellow SHINee member Minho and Girls' Generation's Taeyeonshowed up as attendees, surprising fans everywhere! Fan accounts actually tell us that not only were Minho and Taeyeon present to support Jonghyun and his solo concert tour in Korea, but that they were also both jamming and having a blast during it!

The two artists have satisfied smiles on their faces as they wave their lightsticks around. They're standing up with support banners laid around their heads, while they listen to Jonghyun's directions obediently, such as flashing the flashlight!

SHINee World, who were present at the concert, commented, "I heard Taeyeon-nim really enjoyed the concert a lot", "What do I have to do in my past life to have a noona-dongsaeng relationship like those two?", "They seem like good friends", and so on.

Wish we could've been there!
