Lee Hyori is an animal lover, so it's no surprise that she invited her beloved pet dog to join her 'bad girl' crew.

She shared on her Twitter, "Bad girl and bad Soon Shim," along with a photo of a couple look with her dog. The singer revealed that the special beanie was designed by design duo Steve Yoni, sharing, "Steve Yoni made this hat and top as a congratulatory gift for the release of my 5th album~ They gave me 100 of them to give to my fans, saying I should let everyone wear it and attend the live performance~^^."

Lee Hyori became one of the "Bad Girls" in the MV for her title track, and she also gave fans a sneak peek at her comeback show which will finally air on the 22nd, following the release of her full 5th album on the 21st!
