Jennifer Lopez eyeing $20 million mansion in ex Ben Affleck’s Brentwood neighborhood after split: report

Jenny from the Block might be sharing one with her ex.

Jennifer Lopez is reportedly eyeing a $20 million mansion in her former husband Ben Affleck’s Brentwood neighborhood of Los Angeles.

Lopez recently toured the off-market estate, a source with direct knowledge told TMZ Friday.

The source said the multi-hyphenate “really likes” the property but has “serious concerns” about the air quality around it given the ongoing wildfires that have been burning since Jan. 7.

According to the source, Lopez, 55, is fond enough of the place that she’s bringing in an air quality specialist to assess the area before proceeding with the purchase process.

Reps for the singer-actress did not immediately respond to Page Six’s request for comment.

As for Affleck, the actor-director previously evacuated his $20 million Pacific Palisades mansion that he bought just a few months before the deadly Palisades Fire — the first of many — ignited.

As of Friday evening, the blaze — which destroyed almost the entire neighborhood — was at 77 percent containment, but officials warn of the air quality throughout the entire county.

“Fire debris and ash contain harmful substances like heavy metals, asbestos and toxic chemicals,” LA County Department of Public Health Director Dr. Barbara Ferrer said at a press conference, according to ABC7.

“Heavy metals such as lead and arsenic can come from burned electronics and building materials,” she added, noting that “inhaled over a long period of time, [fire debris] can lead to chronic changes and … respiratory conditions.”

Affleck, 52, temporarily stayed with his first wife, Jennifer Garner, and their three children — Violet, 19, Seraphina, 16, and Samuel, 12 — at the actress’ Brentwood home, even though he has a rental property close by.

He returned to his Pacific Palisades estate on Jan. 8.

Lopez “has been checking in on Ben throughout this whole ordeal” and “let him know she’s there for him and the kids,” an insider previously told Page Six.

Though the once-couple — who were married for two years — finalized their divorce earlier this month, they are still trying to offload their marital mansion in Beverly Hills, which is on the market for a reported $61 million.
