Does Jennifer Garner have another bun in the over? Looks like it. This my friends, is what we call a "Band-Aid" baby!

The mother of three has been out and about in Los Angeles in recent weeks, looking like she is showing signs of being pregnant with her fourth child. Our photogs caught the 42-year-old, wearing a rather baggy sleeveless shirt as she ran errands with her kids in Brentwood, Calif. on Sunday.

The Dallas Buyers Club actress took her wee ones, Samuel, Seraphina and Violet, for some family bonding time near their upscale Los Angeles neighborhood.

The pregnancy is not a surprise to the couple -- apparently Jen and her husband Ben Affleck have been trying to grow their family, reports OK! Magazine.

The couple might not be surprised at the pregnancy news but we certainly are. For months, there have been a wave of reports that the A listers have been having some marital problems -- so adding another yet child into the mix seems like a risky move on Jen's part. Ben's a big-time family man -- and it looks like Daredevil star's giving into her man for the sake of their marriage.

"They have been going through a very rough patch and Jen will do anything to make Ben happy. Having another baby may be their last ditch effort to mend the marriage," reports the magazine.

Despite the obvious signs, Ben and Jen have remained mum on Jen's being a four-time mom.

Good luck to the growing family -- they definitely need it!
