Just after the news of�4minute's comeback delay by a day, the girls have treated us to a video teaser featuring HyunA!

Although the girls left us confused about the final concept with the release of three different sets of comeback photos, it seems they'll be going with the spunky and trendy image depicted in the third set judging by this teaser.

As mentioned previously "What's Your Name?" is the work of none other than�Brave Brothers, and its genre is described to be 'Fantasy Hip Hop', which will apparently go along perfectly with the girl's powerful and charismatic image they'll be showcasing.�According to Cube, the song is an electronic hip hop song with a unique sound and the repeating lines "What's Your Name?" will be hard to forget once you hear it.

It's scheduled for release on 26th, so check out HyunA's teaser while we await the rest!
