Wearing a white long-sleeved shift dress paired with nude heels, the 40-year-old actress seemed to be, well, glowing, on the romantic-comedy movie set! Earlier in the day, Diaz was also photographed smooching her sunglass-wearing costar, Taylor Kinney. Wrapping her arms tightly around 31-year-old Kinney's neck, the actress seemed to be completely engrossed in the steamy scene.
It's actually not the first time Diaz has sported a faux bump; she rocked a pregnant belly in 2011's What to Expect When You're Expecting. But in real life, the sexy blonde is in no rush to bear children -- or tie the knot.
"I'm not sitting there going, 'Oh, my God, when am I going to get married? When am I going to have a baby?'" she told Harper's Bazaar U.K. in 2012. "I would be remiss if I was living my life wishing I had something other than what I have."
She continued, "If, one day, I am blessed with the experience of having a child, I would be overjoyed, but I am not sitting here feeling empty because I haven't yet, or that I may not."
