Can't a girl just get some exercise wearing a form-fitting shirt that hugs her stomach without having rumors of a baby on board?

Apparently not, if you're Scarlett Johansson.

On Sunday Scarlett was getting in some cardio with beau Sean Penn (she seriously dumped Ryan Reynolds for him?) when the paparazzi snapped her mid-jog, her grey fitted tank hugging her stomach with something small protruding from the bottom of her abdomen, sparking speculation she's preggo.

Scarlett's rep said the baby brouhaha is due to her physical activity, telling Us Magazine, "Scarlett is not pregnant.  She's outside running and it's simply the placement of her shirt that is misleading.  She's been training for The Avengers for over four months and is in the best shape of her life."

You be the judge:

Is there a baby on board or is Scarlett the latest victim of an unflattering photo angle?
