Best. Vacation. Ever! Real-life buddies Jo In SungSong Joong Ki, and Lee Kwang Soo all left Korea on June 3 to go on vacation together.

Sharp-eyed netizens saw the three actors together at Incheon International Airport, sparking speculation online about where they could be headed, especially since the three are known as good friends after sharing roles in various projects. 

Lee Kwang Soo and Song Joong Ki have been close for years since their days together on Running Man. Lee Kwang Soo and Jo In Sung were co-stars in last year's hit series It's Okay, That's Love, and Jo In Sung and Song Joong Ki both had roles in the 2008 film A Frozen Flower. 

 As a result of the speculation, the agencies representing all three of them confirmed that they left this morning to go overseas on vacation. The agencies declined to share more information, wanting to give the friends some privacy on their trip. According to an agency representative, "“Because they have left for a personal break, it is difficult to reveal their plans for the trip or the destination." 

On the one hand, I'm happy the agency is giving them space away from fans. They deserve a relaxing vacation as friends, especially since Song Joong Ki just returned from military service. On the other hand, I want to be invited too! 

Doesn't vacationing with these guys sound amazing?
