Jennifer Garner will always keep her tabs on ex-husband Ben Affleck, even after his marriage to Jennifer Lopez.
Garner, who parted ways with Affleck in 2015, 'will always keep an eye on how Ben's doing,' claimed the source.
"[Ben] clearly has a lot going on right now with Jennifer and all the attention that comes with their relationship, along with his demanding career, and of course, his kids," added the source of the couple. "He's being pulled in a lot of directions — and that's something that quietly worries Jen."
Nevertheless, "Jen is happy for Ben," they continued "that's not what this is about," as Garner has no problem with her ex's new wife.
In fact, "both Jennifers get along very well," another added and "has helped positive relations."
