Jane Pitt stunned the movie star's fans earlier this year (12) when she penned an article for her local Missouri newspaper, The Springfield News-Leader, urging her fellow Christians not to vote for President Barack Obama in November's (12) U.S. election - because he supported same-sex marriage.
The piece quickly went viral and led many fans of the writer's son to question whether Jane's opinions negatively affected her relationship with Pitt and her daughter-in-law-to-be Angelina Jolie, who are both big supporters of gay rights and Obama.
Now the Ocean's Eleven star reveals the trio get along just great and respect each others' beliefs, although he confesses they do sometimes talk things out over the dinner table.
He tells People magazine, ""It's a nice, very open discussion. We grew up with a specific set of rules and challenging those rules has never been a closed door. Certainly our views can evolve...
""I come from a Christian family, and (gay marriage) goes against Christian beliefs, as far as what's going to get you into heaven or not. My argument is, that may be as you believe, and it may be true in the end - I don't think so - but let your God make that call.
""In the meantime, we live in a country where everyone should be treated equally, so let's treat everyone equally.""
