Girls' Generation looks so stunning in their new teaser video for their comeback with "Party," "Lion Heart," and "You Think" that you can't help but to just stop and stare at your screen.

They dropped the TV CF version of a teaser video for their comeback. The girls are going for three completely different concepts for their three MVs that will blow your mind away. It's just too much to handle right now (in a good way)!

In the first, the girls look like they could transform into beautiful mermaids at any second, especially Sunny with her bright red hair.  It's perfect for a beach party.  The next one is more mature and glamorous while the last one, the girls strut their stuff and rock it hard, getting super sexy.
