The Bruno Mars song was just released on Tuesday and it is a runaway hit.
It was released on iTunes Tuesday and ranked No. 14 as of Tuesday morning.
Mars has said the single (which was written and co-produced by his band, Smeezingtons) will be "dark."
"The Twilight movies for me [are] a love story. But it's a dark love story. And I think the best way to describe the song is: it's the darker side of love. I think that pretty much sums it up,” he told Billboard.biz.
