So, did some digging last night because I’m giving this show way too much thought.
Jeff’s 1st appearance on Naked and Afraid he was married to Gabby (the love of his life). Not sure when they split up, but Gabby is using her maiden name again, and is still LDS.
Currently, Jeff is smitten with Erin Muñoz, a musician. They have been dating less than a year.
Can’t find mention of divorce on internet, but assume one occurred.
