Dal★Shabet - Pink Rocket [MV]

So the Korean girl group Dal★Shabet has released a new music video for their song "Pink Rocket" off their 2nd mini album. I think the song has some catchy parts here and there. Though I think the most mind blowing part of the experience was when I saw Jessica Jung in pink hair. That caught me off guard cuz I was like, "why does she have pink hair?" Then I remembered this is not a SNSD video. Then it me that either this girl just looks remarkably like her or the South Koreans have managed to clone her. That and whoever is saying the English lyrics kind of sounds like her as well. So somehow they managed to replicate her voice and looks to a certain degree. What is this? I don't even . . .
