**Jennifer Lopez Upset Over Ben Affleck's Post-Divorce Transformation**

Since parting ways with ex-husband Ben Affleck, Jennifer Lopez has been less than thrilled observing his recent lifestyle changes. Following their split, Affleck has embarked on a self-improvement journey, much to Lopez's chagrin.

Known for his scruffier appearance during their brief marriage, often seen with Dunkin' Donuts coffee in one hand and a cigarette in the other, Affleck has cleaned up his act since their divorce in August. Sources reveal that Affleck has embraced a new regimen, focusing on physical and personal care—efforts Lopez reportedly urged him to adopt while they were together.

"Ben is suddenly pampering himself and striving to look his best," an insider told InTouch Weekly. "He's dying his hair, getting manicures and pedicures, waxing, and even consulting a dermatologist for skin treatments."

Further highlighting his transformation, the source noted that Affleck has improved his diet by cutting out junk food, marking a significant departure from his days as the unofficial Dunkin' Donuts ambassador. Lopez, it seems, is both frustrated and hurt by these changes.

"As you can imagine, J. Lo is seeing red," the source continued. "These are all the things she wanted him to do when they were together, but he totally refused. It feels like a total slap in the face to her, as if he wasn't willing to make these changes for her but is now willing to impress other women."

Recognizing Lopez's emotional struggle, her friends and family have rallied around her, emphasizing that Affleck's changes reflect his own issues rather than a personal slight against her. "Everyone is telling her that he's just a middle-aged fool who didn't deserve her," the insider revealed, "but she's still seething and feeling pretty let down."
