But now, the 50-year-old personal trainer has already debuted his "new wife" on Instagram, and fans are not happy.
Nasser shared a photo of himself holding a blonde woman, named Leah, who is kissing him on the cheek.
"New wife... jokingly" he captioned the snap.
Although Nasser has made it clear the he is joking, MAFS fans did not hold back when expressing their opinions on the controversial reality contestant.
"You can't upgrade from the perfection that is Gabby," one user wrote.
Another said, "And you talk about Dean doing all the wrong things and then u put up a caption like that to try and be funny?"
Leah also shared a selfie with Nasser calling him "bae", as well as posting a photo with jilted MAFS groom Ryan Gallagher.
Although Nasser may still be single after ending things with Gab, just last week old footage from TV show Pawn Stars resurfaced where the MAFS contestant talks about his wife and kids.
