OMG > BEAUTIFUL but TOO YOUNG

So if you havent heard will smiths daughter willow got the rihanna cassie kinda cut and it looks AMAZING on her. But the girl is only 7!!. im 17 and i still wasnt sure if i wanted to cut my hair. I feel like shes way too young to shave her head. shes gonna have those days when she wants to do something cute and girly and gonna nag and regret her hair what are they gonna do then? It does look beautiful on her though. It fits her face and lets face it her and her brother are GORGEOUS kids. So the look is cute but wrong age. I think
