5.Double Scoop:

And the award for the most overexposed bosom in Hollywood goes to ... Scarlett Johansson! The pneumatic starlet's exhausted assets should stage a cleavage coup and start demanding a portion of her paycheck, 'cause lately they seem to be doing much of the heavy lifting (here, they get a little help from the built-in pushup bra sewn into her sexy but run-of-the-mill red Valentino gown). Though there's nothing wrong with Scarlett showing off the preternatural perkiness found only in 21-year-old It Girls (as verified by a touchy-feely Isaac Mizrahi on the red carpet), she seems to think the phrase "taking it on the chin" means cramming her breasts into a breathtaking scoop neck bodice (and we mean that "breathtaking" part literally) and jacking them up to gravity-defying heights.
