The actor and his former fiancée Lopez, (remember Bennifer?) continue to exchange friendly emails.
He told the Hollywood Reporter, "We don't have the kind of relationship where she relies on me for advice, but we do have the kind of relationship where there'll be an email saying, 'Oh, your movie looks great.'"
Affleck continued, "I remember when she got 'American Idol.' I said: 'This was really smart. Good luck.' I touch base. I respect her. I like her. She's put up with some stuff that was unfair in her life, and I'm really pleased to see her successful."
Of course, Garner remains his No. 1. "She truly is kind… she means no one any harm. She doesn’t have ill will for any person. She’s not competitive with other people. She’s not spiteful."
"Argo" opens Friday, October 12.
“Argo” star and director Ben Affleck has been married to Jennifer Garner since 2005, but says he’s still on civil terms with exes Jennifer Lopez, Gwyneth Paltrow and high school girlfriend Cheyenne Rothman.
