During a live taping ofWhitney Port‘s podcast,With Whit,on Thursday in Los Angeles, Carter said she andBrody Jennerdecided to sign on toThe Hillsrebootin hopes that it would bring them closer together as a couple.

“The decision really was about whether for us to be able to spend more time together,” she continued. “Because he was always on the road deejaying and I was always on the road with for work withForay. So this was like a project together.”

While Carter, 30, said she was excited about the idea of working with her then-husband, a source previously told PEOPLE the show had a negative impact on their already fragile relationship.
