Stellar's MV teaser for "Sting" is out and the girls are classier and hotter than they've ever been before.

The members are like models walking down a runway, as they wear high fashion and heels and walk down a hallway.

They sing, "Do my words sting? Are you sick of our relationship?" Their song "Sting" already sounds so catchy.

The video that was released before showed some clips of their MV, but it was an 'M! Countdown' preview for their comeback stage. This is their first MV teaser, so be sure to watch it above!
