Girl group Stellar are preparing for their comeback, and to launch their new phase of promotions, they've released the MV teaser for "UFO"!

As reported earlier, Jun Jin helped out his fellow Shinhwa member Eric by guest-acting in his girl group's video.

The teaser for "UFO" sees Jun Jin and Stellar member Ga Young having a heated moment outside; Ga Young tries to leave but Jun Jin pulls her back into his arms. The teaser fades out just as the two are about to share a soft kiss.

Stay tuned for more updates on Stellar's comeback!
