But that almost changed on Tuesday when the Oscar winner nearly suffered a double nip slip—or a whole boob pop-out—on the set of David O. Russell's untitled film in Boston.
In a shot from set, Jennifer's plunging white dress struggles to keep her assets contained. But impressive cleavage isn't the only thing going on with Jen's look here: She's wearing a fur coat (hopefully fake) and humongous gold and diamond teardrop earrings. Her blond hair is even curled and pulled into a dated updo, giving her an overall campy glam appearance.
If Jen's girls had made an appearance, we're sure her costar Bradley Cooper—and for that matter, anyone on set—wouldn't have minded one bit.
