Girls' Generation's coupling track 'Do The Catwalk' revealed

Girls' Generation had already released the PV for their new Japanese title song 'Galaxy Supernova' earlier this month and the coupling track has been revealed.

The track, 'Do the Catwalk' is just as catchy, but a little more laid back and cute. Check out both songs if you haven't already to see if you'll be dancing and whistling along to their upbeat tunes.
