Jen & Ben: TOGETHER AGAIN?!

Now that JENNIFER LOPEZ is single again, she’s been spending time with her ex-boyfriend BEN AFFLECK.

He’s been spotted several times being driven to her home in a white Escalade that supposedly belongs to her.

It should be noted that these are DAYTIME visits, and a source says they’re JUST FRIENDS, which they’ve been since they broke off their engagement in 2004.

FYI, Ben’s ex-wife JENNIFER GARNER is aware of these “friendly” visits, and she’s cool.  A source says, quote, “She wants what is best for Ben.  What matters most to her is Ben being a great dad.”
