Yuri and Sooyoung Have a Lip Sync-Off to Christina Aguilera in Preview for “Channel Girls’ Generation”

In new previews (below) for Girls’ Generation‘s upcoming OnStyle reality show “Channel Girls’ Generation,” the girls turn their car ride into a karaoke fest as they jam to Christina Aguilera‘s international hit “Come on Over (All I Want Is You).”
