Dancing With the Stars romance alert!

ET has exclusively learned that there's a budding romance in the DWTS ballroom this season between contestant Paige VanZant and troupe member Alan Bersten -- and we've got all the details!

A source close to the couple tells ET that their connection is "still new" and the attraction between the 22-year-old UFC fighter and the 21-year-old professional dancer has been building all season.

"They just got to know one another during the show and rehearsal [and] they took a liking to one another," the source dishes exclusively to ET. "They aren’t really showing it off, but they are definitely interested in one another."

The twosome first became close when VanZant's usual professional partner, Mark Ballas, was injured and could not dance in the second week of the season. Bersten stepped up to fill in for Ballas, and together, he and VanZant delivered one of the top dances of the week with their ultra-steamy salsa.

"Still in shock with how amazing @paigevanzantufc did tonight!" Bersten gushed on Instagram after their performance along with an adorable photo. "Thank you for sharing this beautiful moment with me."

VanZant shared her own picture-perfect Instagram, writing, "WE DID IT!!!! @alanbersten stepped up so I can dance another day. @markballas is healing up!!! Hope we put on a spicy show to get your votes tonight. Xoxoxo"

Since their dancing debut, VanZant and Bersten have been spotted looking like they're definitely more than friends at the weekly DWTS after-parties at Mixology 101 in Los Angeles. The duo keeps the PDA to a minimum, but they're always are seen arriving and leaving the parties together with smiles on their faces.

Dancing With the Stars airs Mondays at 8 p.m. ET/PT on ABC.
