f(x)'s appearance on part 2 of Radio Star just aired today, and Victoria impressed the audience again! Her flexibility smacks peoples' faces as they watch in awe of her skills, which perhaps may be up-to-par with world record-breaking figure skater, Kim Yu Na. On this episode, she also displayed her tumbling skills, which is something that could not be easily done. Adding on, the f(x) members humorously shared, "Victoria also has a sleeping habit of stretching. One time, while she was sleeping, her leg was right next to her ear." Meanwhile, the other members also showed off their various talents: Amber doing a dope rap to Eminem's Lose Yourself, Sulli and Krystal dancing along to Britney Spears' Womanizer, and Luna showcasing her powerful vocals through Ann's One Sided Love and Whitney Houston's One Moment in Time.
