Singer Lee Hyori is preparing for a 2013 comeback and she just dropped some hints at her upcoming album.

On February 9th, Lee Hyori posted on her official fan cafe, “Preparation for the new album is going fine. There are many difficulties in creating a full-length album. I thought about just releasing a digital single or a mini album, but I thought I should keep on pushing myself.”

The singer continued, “The album has over ten songs, so don’t get sick of it and listen to them all. I feel like I should make something a bit heavy. I think I should be back around this summer.”
