Perhaps he should have waited to light up until he was alone?

Ben Affleck and Jennifer Garner went for a stroll around their Brentwood neighborhood yesterday afternoon, and the actor couldn't resist puffing away on a cigarette just feet away from his ex. You'd think he care about exposing the mother of his children to second-hand smoke, but apparently not!

The actor has been trying to focus on his sobriety and career in recent months, and a new report claims the Batman star wants to reinvent himself and dip his toes into the comedy world. The problem? He won't leave Kristen Wiig alone about co-starring in a flick with him, and it's making her uncomfortable given her ties to his SNL producer girlfriend Lindsay Shookus.

"Ben’s not known for comedy. He’s become obsessed with the idea that he should lighten up, so he’s been bombarding Kristen with calls and texts. She feels obligated to reply, but doesn’t want to upset Lindsay," a source dished to OK! magazine.

Their divorce might have been a blessing in disguise for Jen G!
