After looking at these photos, we HAVE to ask!

Ben Affleck and Jennifer Garner cheered on their 4-year-old daughter Seraphina at a kiddie track meet in Pacific Palisades over the weekend, and we can't help but notice that Jen is looking a bit round in the tummy region! Is there any way that the couple are expecting a fourth child? Or did we simply catch Jen minus the Spanx?

Jen gave birth to son Samuel in late February of 2012, and last September she appeared on The Ellen DeGeneres Show and revealed that Ben has always been eager to have lots of kids. "I plan to be done," she said. "But my husband is kind of a wonder sperm kind of guy." She hasn't exactly ruled it out!
