Irina Shayk Has Craving for Ice Cream, Hiding Baby Bump

Irina Shayk's employing the oldest trick in the book -- super baggy sweaters -- to conceal what's widely believed to be the baby in her belly, but her mouth is blowing the secret.

Irina was out Sunday in L.A. with BF Bradley Cooper's mom and couldn't resist sucking down an ice cream cone during a grocery run. Cravings much?

She and Bradley have been tight-lipped about the pregnancy rumors, but frozen desserts -- on a chilly day in L.A. -- and this profile shot kinda tell the story, no?

One thing's for sure ... it's gonna be a really, really, really good-looking baby.
