help me please..

I'm looking for a music that the chorus is "this must be a loooooooove..." and then the man say something and again "this must be a loooooooove" and say another thing, that I don't understand. than, during the song I get some expressions like: "take my love", "Walk away", "olsen twins" and "I love you".
Well...I really wanted to know who sings this...this is the second time I'm asking. it's not roxette or madness song, it's another completly diferent... dance music and the man's voice is kind Gnarls Barkley.

hope you help me!!!
