SNSD′s Seohyun is Officially All Grown Up

Girls’ Generation (SNSD)’s Seohyun got the party started early with her label mates earlier this week, but SNSD’s youngest member actually turns 21 years old today.

Seohyun’s fans wished her a happy birthday through a special newspaper ad printed on June 28, which contained the message, “We gaze at a blue sky that is as bright as your smile, as pure as your heart and as deep as your love. Our hearts are with you wherever your songs go. Happy Birthday Seohyun.”

We have watched Seohyun blossom into a beautiful starlet over the years, and in celebration of our favorite goodie two shoes’ birthday, we’ve gathered some childhood photos of the idol star.

It′s apparently possible for people to look cute in school photos. Sigh.

That′s a model student if we ever saw one.

Do we spot a girl group member in the making? She definitely has the pose down.

Gasp! Is Seohyun′s face actually smaller than Yoona′s?

Not many people can say they shot an ad with Park Yoo Chun before they became a member of SNSD...or that they′re a member of SNSD we guess....

And finally, it′s not your birthday unless you′re wearing a tiara.

Happy birthday Seohyun!
