I have black hairs but have fun in blonds-Amber Rose

Who knew Amber Rose has natural black hairs.She put this on her page saying that she was born with her hairs black ,but it shows she is more comfortable with blond hair because of the fun she attached to it.See what she said:
"Most ppl don't know that I naturally have really dark hair...... Always wanted to be blonde tho. Blondes have more fun! 😝 "
Which one could look better on her,blond or black?
