Ben Affleck -- Even Jennifer Garner Doesn't Believe He Messed with JLo

Jennifer Garner has issues with Ben Affleck for sure, but they have nothing to do with Ben's former fiancee, Jennifer Lopez.

Sources directly connected with the couple tell us, neither Ben nor Jen have even raised JLo's name in their decision to divorce. More specifically, we're told Garner has no issue on that front ... it's not about JLo.

The stories about Ben and JLo started circulating after Ben walked over to Jen during the Oscars, said something, and walked away as she brushed his arm.

That said, on the other hand, our sources will not say Ben and Jen never argued about other people during their marriage.
