Jennifer Garner's boyfriend, John Miller, appears to show 'insecurity,' a body language expert says. Here's why.

Jennifer Garner assures boyfriend John Miller there's no need for concern after being seen with ex-husband Ben Affleck. Garner clarifies the encounter was harmless and their relationship remains strong.

Speculation swirled in February that Affleck was keen to reunite with Garner after they were spotted bonding on multiple occasions in the subsequent months after his divorce from Jennifer Lopez. (Affleck and Lopez, 55, settled their divorce in January after two years of marriage.)
