“Jennifer is putting her foot down and saying no way,” the insider spilled.

There’s no evidence Affleck has ever tried to hook up with Vergara, but the tipster claims the smitten Good Will Hunting star’s appreciation for the “total smoke show” has “triggered” Lopez’s “insecurities” — especially because their first romance hit the rocks in 2003 over the Gone Girl stud’s alleged infidelity!

In a recent interview, the On the Floor singer admitted she’d step up to ANY competition and warned, “Do not play with me!”

“I’m a lover, not a fighter, but I will let them know in a very elegant and ladylike way to step ALL the way off!” Lopez declared of protecting her marriage.

As this outlet reported, Lopez got candid about her past abusive relationships and insecurities in her new documentary, The Greatest Love Story Never Told.

“There were people in my life who said ‘I love you’ and then didn’t do things that were kind of in line with the word ‘love,’” Lopez confessed. “You have to hit rock bottom where you’re in situations so uncomfortable and so painful that you finally go, ‘I don’t want this anymore.’”
