Jennifer Garner gas sweats tshirt no makeup

Supermom Jen Garner - after spending time with daughter Violet on her 5-year wedding anniversary to hubby Ben Affleck - was just going about her day (in a pair of sweats and without any makeup, no less) when she stopped to help a neighbor after she ran out of gas...

What a Good Samaritan! Not to mention good celebrity. Whether or not she's preggers with her third child or had a not-so-great anniversary, Jennifer still made sure to help out someone in need.

I'm sure the driver was also pretty excited when they found out their guardian angel was a famous Hollywood actress!
