Tough as nails on the outside but softer than any other with a tender heart on the inside, Lee Hyori is truly fatally attractive.

Appearing on talk show 'Happy Together' along with her best friends, Lee Hyori reminded the fans what sets her apart from other celebrities: well-meaning candor. At all times, on and off camera, she seems to be one of the few stars who are their true selves. Of course, she is also one of the few who could afford to be themselves.

Hyori's friends who appeared on the show shared personal stories about the sexy queen. An Hye Gyung told that Lee Hyori never responds to texts and makes it very difficult to tell whether they are confirmed for their dinners and meetings. To this, Lee Hyori  said that when Lee Sang Soon, her boyfriend, texts her "I love you" she just thinks to herself, "I guess he loves me," and does not answer the text.

When the host asked, "Don't you think you need to give him that affirmation?" she replied, "No, I am a bad girl. Lee Sang Soon, you think I'm yours? Don't let up," prompting everyone to a huge laughter.

An Hye Gyung shared Lee Hyori's tender, caring side about the time when she visited An Hye Hyung's hospitalized mother on Christmas Day. About the 2-hour drive, Lee Hyori remarked, "An Hye Gyung had been having a tough time looking after her mother for a while, so I wanted to do something for her when I found out she would spend Christmas at the hospital."
