Britney Spears has traded in her blonde locks for a brunette 'do.

The singer sported a new darker look as she stepped out for a spot of shopping at Bed Bath & Beyond with her agent and rumoured beau Jason Trawick.  

And the brown dye-job didn't come too soon for Brit's abused locks – just two days previously her hair was looking completely frazzled as she was snapped while out and about in L.A., again with Jason.

On both occasions, the star – who wore the same denim hotpants and orange-rimmed shades – made sure snappers got a good look at the rock on her left hand, prompting rumours that she is to marry for the third time.
