Girl group Girls' Generation's member Yoona talked about her skinny waist.

In KBS 2TV "Entertainment Relay," Girls' Generation's Yoona, Super Junior's Kyuhyun, and f(x)'s Sulli filming for a commercial were visited.

Yoona had previously caught much attention during 'Dream Concert' last week with her bold see-through look with her skinny waist and abs.

The reporter said, "Are you now in charge of sexiness in Girls' Generation?" and Yoona blushed shyly.

The reporter also complimented Yoona's waist, asking "How do you maintain it?" and Yoona said, "It's not like I do anything to take care of it."
