FORGET umbrellas, RIHANNA'S in need of a woolly hat.

RIHANNA babe unveiled her new shaved hairdo in New York yesterday.

Though equally eye-catching was the sight of her bra beneath her see-through top. Still, she'll need to invest in some thick headwear if she plans on going skiing this winter.

Fortunately, the singer's hair cull was restricted to the sides only, leaving her trademark angular locks on top unscathed.
