IU recently released a short but sweet CF for Samsung's Galaxy S2. The rising star was seen playing with the new cell phone model, which apparently got more 'fun'. She and a male model flirted with each other by utilizing the new 'Motion UI' on the phone. As IU pulled the phone closer to her face, the image on the phone got bigger, and then smaller as she pulled it back. Her adorable personality shone through in the CF, as well as her elegant beauty, which was emphasized by her bright blue dress. Check out the CF below: Thanks to Tracy for the tip!
