Is Jennifer Garner pregnant again with baby number 4? Jennifer Garner sparked pregnancy rumors Thursday when she was photographed in Los Angeles showing off what appeared to be a growing baby bump. Looks like Ben Affleck and his wife may have another baby on the way!

Jennifer Garner wore a dark blue striped tank, green army pants, sunglasses, and had her hair in a bun while she chatted on her cell phone in Los Angeles last week. The tanktop wasn't too tight, but you can see Jen's belly bulging beneath her shirt. Otherwise quite thin, the 42-year-old "Alias" actress seems to be sporting a growing baby bump!

Meanwhile, husband Ben Affleck is in Detroit shooting "Batman v Superman: Dawn of Justice," in which he is playing the coveted role of Batman. The film is set to release 2016.

Will they have four kids by that time?

According to Momtastic.com, Jennifer Garner revealed that she wasn't planning on having a baby number 4. At "The Odd Life of Timothy Green," movie premiere, Jennifer admitted life with three kids can be hectic.

"It's absolute chaos!! I really did not realize how much more work three was going to be than two."

"The fact that Ben wants another IS true," she revealed. "I can tell you that would be a pretty uphill battle with me. I am not anticipating having any more kids!"

Life is full of surprises!
