Ben Affleck and Jennifer Lopez Go Mansion Shopping, $65 Million Home in Running

8:29 PM PT — A source close to the couple tells this publication — Ben, being the good boyfriend he is, was accompanying J Lo on her own hunt for a mega-mansion — the two aren’t ready to shack up together … at least not yet.

Ben Affleck and Jennifer Lopez like it, and they’re about to put a ring on it — a housekey ring … because the couple’s jumping to the house hunting stage of their reunion!!!

Bennifer 2.0 was out and about Thursday in L.A.’s upscale Holmby Hills neighborhood, and they had a high-end realtor escorting them to check out a few mansions. J Lo and Ben followed in their own vehicle, stealing a few kisses along the route … perhaps to celebrate finding their dream home.

We know one of the pads they toured is a $65 million, 31,000 square-foot palace with 8 bedrooms and 12 bathrooms. That’s tons of room for them and their 5 kids … who we’re sure would love some of its fun features.

The pad’s got a freakin’ bowling alley!

Our sources say the couple checked out at least 3 mansions during the shopping trip, which comes a little more than 2 months after they grabbed headlines again by hanging out in Montana … shortly after J Lo’s split from A-Rod.

They’ve been pretty inseparable ever since … including a romantic hook-up in Miami, date night in Beverly Hills … and a trip to the Hamptons with Jen’s kids.

Ben even had his children hanging with J Lo’s daughter, Emme, last weekend at Universal City Walk for some modern family fun.

All that, along with Jennifer visiting schools in L.A., and ya gotta think it’s only a matter a time before they’re all living under one roof. And, what a luxurious roof it will be.
