What song am I talking about?

Okay, I honestly cannot, for the love of God, remember the name of
this song! Not even the lyrics! I just remember I used to really like
it, and the music video for it.

All I can remember about it is the music video. If I remember
correctly, the singer (a girl) kept killing her boyfriends, in various
ways. In the video she killed 3 of them, one of them by poisoning him
(I think) and another by dropping bricks on him. In all 3 of the
deaths, an apple was always some where on the scene. Also, the boys
were cheating on her (I think). Oh, and the only "visible" one was the
singer, all the rest were shadow figures, I guess. Not literal
shadows, just... you know what I mean right? The music video was
always accompanied by the music video for "Chasing Pavements" by
Adelle in the top 10 music video count down on Vh1.

One more thing! The title was "long for a song name" I guess, it had
the words something or someone, and always or anyone or anyway in it!
Also, no, it is not "It's my Life!" by No Doubt, but that is a good
song...

Sorry, if I'm not being very descriptive... But thanks to any and all
who help! :D
