Maloof recently revealed that she will be back on the show this fall. "It just made sense to maybe take this and come full circle from where I left off last time," Maloof told Us Weekly in early August. "I'm coming back, also, a bit wiser. I know what to expect now. There were some unfinished situations that I felt the need to kind of mend and come full circle."

"A lot has happened in my life," Maloof continued saying about her return. "So with each experience, I think I've grown. I'm at a point now where it's a new chapter. I can really focus and think clearer on what to expect, and there's nothing like experience to kind of get you to where you know you want to be."
