"It's not serious," the source says. "They met on 'Famously Single.' It's very new -- they're both having fun."

Earlier this month, the former Danity Kane lead singer, 31, posted a photo to Instagram of herself snuggling with her new beau, 35, but the pic has since been deleted. Instead of those shots, there are now snaps posted five days ago of the cute couple in matching shoes.

The reality stars have been cooped up together in the same house for about a month for their new show, "Famously Single," which also stars Brandi Glanville, "Bachelorette" star Josh Murray and former NFL running back Willis McGahee.
