U-KISS, which stands for Ubiquitous Korean International idol Super Star, released a teaser image for their upcoming album on May 26.

The 7-member boy group is joining the hot list of comeback artists for the month of June. 

The newest member of U-Kiss, Joon, is included in their teaser image for "Mono Scandal."

U-KISS fans found out a little too early about Joon's addition to the group after a staff member leaked a photo of him with the other idol members.

"We regret that the photo of the new member was leaked due to a mistake by the staff. The new member will join during promotions for the album releasing in June. Following the leave of U-KISS' maknae Dongho, this person will surely fill in the empty space. Look forward to the transformed U-KISS," stated the group's agency, NH Media, on May 15.

Donghae, the group's original maknae, left the idol band in 2013 because of medical reasons.

For those who have yet to hear about Joon, the new "makenae" of U-Kiss was born in 1987 and is 6'1" (185cm). He has been noted as a talented addition to the K-Pop group because he can both sing and dance.

Once the members of the group begin promoting, AJ will not be a part of the schedule because he is currently working on his studies at Columbia University.

Their new album titled "Mono Scandal" is going to be released on June 2nd.

The group, which is comprised of members Soohyun (Shin Soohyun), Kiseop (Lee Kiseop), Eli (Kim Kyoungjae), AJ (Kim Jaeseop), Hoon (Yeo Hoonmin), Kevin (Woo Sunghyun) and new member Joon, is currently working with composer Duble Sidekick. Their new single will be titled "Don't Flirt."

Fans should know that the U-KISS that they knew before will be coming back with a new and improved concept.

"As much as this is the sixth year since their debut, they will show unprecedented music that is different from that of idol groups. The MV is by the director Lee Duk Hee of the movie 'Changsoo' ('Tumbleweed')," stated NH Media.
