Although Girls' Generation made their domestic debut on August 5, 2007, they celebrated their seventh anniversary early with an awesome six-tier cake and a sweet party featuring a lot of pretty pink and all gorgeous nine members.

This party was covered on Japanese TV show, 'Another Sky,' and the cute pictures were uploaded onto the girls' official Japanese Twitter.  The girls look super happy as they wear balloon crowns and pose closely together with heart and V-signs.

Congratulations in advance to Girls' Generation on their successful seven-year career!
