I'm not certain that anybody could accuse Britney Spears of viewing the world through rose colored glasses, but there WAS a sighting of her in silver aviator style sunglasses with what seemed to be pink (or rose) colored lenses.
The lenses may have been heavier on the tears, longer in shape on the sides and I don't believe that there was a mirror effect on the lense because her eyes were very visible. The nose piece was not thick like Ray-Ban aviators, but that may have been the case.
I liked the sunglasses, but the real news is that she appeared to have enough new growth of hair to have allowed her to be without her wig. Her hair color is a brassy blonde which was a real switch from the dark brown wigs that she has seemed to favor during her bald stage.
