Wonder Girls' Yenny underwent a dramatic hair transformation! The star revealed that she's cut her hair short for the first time since she's debuted with the group.

Yenny tweeted, "The first�bob cut [I've had]�in 10 years + my first bangs in 4 years = rejuvenation," along with the above photo.

The Wonder Girls member seems to look even younger with a sandy-colored bob cut and front bangs. Fans are impressed with the new fresh look as they've never seen Yenny with a short hairstyle before.

Followers commented, "Why didn't you have a bob cut until now. It's so pretty," "What do you mean 'rejuvenation', aren't you still young?" and "Cut her bangs, and such a cute expression! So pretty."
