Jennifer Garner gym workout gross sweat mess Awkward alert!

Jennifer Garner left the gym after workout in L.A. this morning, and she must have been embarrassed to be all sweaty with no makeup on, because she randomly passed Toby Maguire and his son Otis on the street and she completely ignored him!

Jen G pulled the classic "I'm too busy texting to notice my surroundings" trick!

We would assume the two stars know each other, too! After all, the Spiderman actor used to play underground poker with the brunette beauty's hubby Ben Affleck.

Maybe next time she won't give him the cold shoulder!
