Ben and Jennifer were together from 2002 until 2004

But just a few days before they were due to tie the knot in September 2003, they called off the wedding because of "excessive media attention". They eventually decided to split in January 2004 with Jennifer later describing their breakup as her "first real heartache".

Just a few weeks ago, Ben, 48, was photographed by Page Six exiting Jennifer's white Escalade SUV. While they were not pictured together in the car, sources told the publication that "security picks him up at a nearby location and drops him off after spending a few hours at her house".
