I can only remember the video. The singer is female with short bleached blonde hair, in a mohawk style. In the video everyone is dressed in white and the room is also white. There are guards to make sure the people don't interact. When a girl tries to get close to a guy, the guards pull them away from each other and the girl screams and gets mad. Some ideas anyone? Thanks

I don't know if this will help, but I think it could be P!nk or Britney Spears.

Nope , I'm sure it's not P!nk or Britney Spears, the singer I'm looking for is not as well known as they are, but thanks anyway :)

Could it be Emeli Sande?
