Jennifer Lopez is reportedly unhappy with Ben Affleck's close relationship with his ex-wife, Jennifer Garner, as he confides in her about their marital troubles. According to a source, the 54-year-old singer has made it clear that she does not want Garner's input on their personal issues.

"Everyone knows that Ben and Jen remained very close after their divorce. He confides in Jen about everything, even his issues with J.Lo," the source revealed. "J.Lo hates that Ben goes back to his sensible, down-to-earth ex-wife for advice and emotional support. She doesn't want Jen's input."

Lopez has allegedly conveyed her disapproval to Affleck, with the source adding, "J.Lo didn't come right out and tell Jen to back off – both women have been down this road before and know their boundaries – but she did tell Ben that his ex needs to stay away from him and butt out of their personal drama. Ben then relayed the message to Jen."

The tension between Lopez and Garner comes amid reports of Affleck living separately from his wife in a $100,000-a-month Brentwood mansion due to relationship troubles. The couple, who rekindled their romance from the early 2000s and tied the knot in July 2022, has been facing challenges as low-key Affleck struggles to keep up with Lopez's very public lifestyle.

Despite their divorce in 2015, Garner still cares deeply for Affleck and hates to see him suffering. "Jen would never tell Ben, 'I told you it wouldn't work out,' but she does blame J.Lo for the pressure she's put Ben under," the source noted. "She sees how Ben struggles with keeping up with J.Lo's very public lifestyle."

While Garner initially tried to stay out of her ex-husband's relationship issues, she doesn't want to see him fall back into destructive behaviors, such as substance abuse and gambling, which he has struggled with in the past. The source added, "Jen can't stand by and do nothing. That's not in her nature. She has dropped everything to make sure Ben doesn't spiral out of control again. At the end of the day, Ben is still the father of their children, and she will help him however she can."

The news of Lopez and Affleck's marital troubles comes as the singer recently canceled her "THIS IS ME...LIVE" tour. Representatives for Live Nation explained that Lopez would be "taking time off to be with her children, family and close friends." In her newsletter, Lopez expressed her heartbreak and devastation over letting her fans down, promising to make it up to them in the future.

Rumors of a separation intensified after Affleck skipped out on the Met Gala with Lopez, who showed up solo for the event she co-chaired. The couple had not been photographed together for 47 days until they attended an event with their children on May 16.

Sources suggest that the couple's differing parenting styles may be contributing to their marital issues. "They've had fights about differences of opinions on raising their kids," a source told Fox News Digital. "They have very different parenting styles."
