BeyonceIs Beyonce Knowles attending a fancy dress party?

If so, what is she meant to be?

A sexy alien or an evil mermaid?

That's what we thought until we realised that Miss Knowles is actually filming her new video, and now we are just plain confused.

While we love Bey's new tunes, we are not quite sure about these bizarre outfits.

Recently Beyonce has been going down a little bit of an alternative route, as she explained in a recent letter to her fans:

"The music is upbeat for the dance, fun side and it is reflective, passionate and serious for the personal side," she said.

"I have taken risks here. I am not afraid and my music will explain it all."

Well she certainly has made her point, especially with that strange apparatus attached to her head.Beyonce

Maybe it was her racy alter ego's idea of style?

The diva, in a concerted effort to build upon her iconic status, has now insisted to be known as Sasha Fierce when she performs.

We first met her doppelganger at the MTV Europe Music Awards when she wore that freaky cyborg glove.

We wonder what Jay-Z thinks? Maybe he is into that sort of thing...
