Olivia Culpo is already working on her post-pregnancy body, it seems. "Here goes my diet," Olivia, 33, said in an Instagram Stories video on Wednesday, July 23. The clip showed her mom, Susan Culpo, bringing her multiple desserts. The snacks appeared to be a rather decadent looking chocolate chip cookie and blondie. "I told her I'm on a diet," Olivia captioned the post, adding a skull emoji. The clip came nearly one week after Olivia announced that she and husband Christian McCaffrey welcomed their first child.
