Singer BoA revealed a picture online from her Europe vacation.

Yesterday she posted on her twitter, "I wonder what this BOA mean. haha," along with a picture.

In the picture, the words 'BOA' are seen written on a wall in Europe. BoA is wearing sneakers and jeans and a beanie for a tough and boyish look.

Internet users commented, "Maybe your fans wrote that?" and "We love you BoA."

On the other hand, she will begin her global portion of her solo concert starting in Taiwan.
