While her ex-husband is getting steamy with Jennifer Lopez, Jennifer Garner is thriving in her $14 million mansion rental.

Garner, 49, is renting a Pacific Palisades, California, mansion while she waits for construction to finish on her new Brentwood mansion located near ex-husband Ben Affleck, 48. They are parents to their three children — 15-year-old Violet, 12-year-old Seraphina and 9-year-old Samuel.

The six-bedroom, 7½-bathroom rented home spans 10,500 square feet, according to the listing. It is unknown how much the “Alias” actress is shelling out for the rental, but the residence’s monthly rent is estimated to be $53,271, according to Zillow.

The white house with bay windows was built in 2009 and was formerly owned by cosmetics heir Dean Factor and his wife, Shannon, before being purchased by the current investor-owner for $13.86 million, according to property records.

The white home has neoclassical columns holding up a peaked covered entry. On each side are second-floor terraces over bay windows. The facade also has several dormer windows.Realtor.com

The rental is temporary while the “13 Going on 30” star, who was most recently reportedly dating CaliBurger CEO John Miller, finishes building her new Brentwood home, which she purchased for $7.88 million in 2019, The Post previously reported. She and Miller are not known to be living together.

“I’ve learned that I’m pretty sturdy,” she told People in March, before it was revealed that she and Miller had reconnected romantically after a yearlong break. “I’m OK when I’m in the house by myself. I’m OK when it’s just the kids and me. I’m okay when they fall apart. I mean I have my moments, but pretty much, I’m really OK.”

Garner previously owned a $32 million mansion with Affleck, whom she married in 2005, and from whom she was separated in 2015 and divorced in 2018. The “Batman” actor, who is in recovery from alcohol addiction, called the divorce the “biggest regret of my life.” Child advocate Garner was previously married to “Scandal” actor Scott Foley from 2000 to 2004.

The main level also has a theater outfitted with purple curtains, a grand guest suite and an office, according to Realtor.com.Realtor.coPREVIOUS

Affleck dated and was engaged to 51-year-old Jennifer Lopez from 2002 to 2004. The pair allegedly struck up an email correspondence in February, two months before she split from her ex-fiancé, 45-year-old former Yankee Alex Rodriguez.

The Post has reached out to Garner representatives for comment.
