WATCH NOW! Beyonce acts weird at basketball game

Beyonce has been in this biz for a long time and knows how to work the cameras.

But recent footage of her at a basketball game sitting alongside hubby, Jay Z, has raised eyebrows.

Why? Well, B sits nodding her head along to music. Except there is no music.

And she looks really, er, spaced out...

Bad day? Zoned out? Call it what you want, but watch this vid and decide for yourself...
