Scarlett Johansson, you sly devil! The actress, reportedly pregnant with her first child, did a bang up job of mostly concealing her alleged baby bump in a lace top with a bow at last night's (March 13) premiere of 'Captain America: The Winter Soldier' in L.A.

It's almost like a "Did she or did't she debut her baby bump?" scenario, since she's not cradling her tummy like most moms-to-be. And then there is that bow, which obscures her silhouette.

The pouty-lipped, curvy-hipped actress wore a white Giorgio Armani Prive lace top with cap sleeves and a black bow, strategically placed in the middle of her chest, right under her cleavage. She paired it with a black, pencil-shaped lace skirt, which showed off her derriere.

However, in certain angles, she looked fuller in the tummy. And her cleavage? Well that was totally amazing and awe-inspiring.

Scar Jo has always had enviable curves, but she looked even curvier last night.

The black lace skirt is very slimming and makes for an optical illusion.
