The Mad Max star blasted Jews in front of a Jewish highway patrolman, who had arrested Gibson for driving drunk in Malibu, California.
Gibson has since apologized for his remarks and called for Jewish community groups, who are furious with him, to help him save his good name.
And now, amid all the criticism, levelheaded Foster has offered the troubled star, who checked in to rehab earlier this week, her support.
She tells the Los Angeles Times that she doubts claims that Gibson is prejudiced against Jews.
She says, "Is he an anti-Semite? Absolutely not, but it's no secret that he has always fought a terrible battle with alcoholism."
"He took his recovery very seriously, which is why I know he is strong enough to get through this now."
