The Unpacked Drama Between Witney Carson and Mark Ballas on DWTS Season 21

When Alexa and Carlos PenaVega sat down for their October 22 episode of the LexLos podcast, they didn’t just reminisce about their own ballroom battles. They also opened a dusty folder of behind‑the‑scenes gossip from DWTS season 21, naming pros Witney Carson and Mark Ballas as the unlikely source of tension.

According to Alexa, the two danced not just on the floor but also around each other like they’d been told to stay on opposite sides of a line. “Witney and Mark were not getting along at all. They actually refused to be in the same room together,” she said, chuckling before adding that it made things awkward for the married couple, who were paired with the two pros respectively.

Fans have been trying to piece together why the feud started. The most common theory points to a rumored fling in 2014, a time when both were supposedly on a break from their own relationships—Witney from her high‑school sweetheart Carson McAllister (engaged later that year) and Mark from his then‑fiancée singer B.C. Jean (engaged in November 2015).

There’s some circumstantial evidence that fuels the speculation. In October 2014, Mark threw a surprise 21st‑birthday party for Witney, a moment captured in an Instagram post shared by fellow dancer Jenna Johnson. Later that year, during the DWTS tour, the two performed a Travis Wall contemporary routine that ended with a kiss, a clip that still circulates on YouTube.

Even more suggestive was a now‑deleted Instagram tribute Mark posted in September 2014 after they danced to Smokey Robinson and Aloe Blacc’s “My Girl.” He wrote, “Loved dancing with this little one tonight @witneycarson… I remember thinking ‘this one’s gonna do big things one day.’” The affection in that caption feels more personal than professional, at least to casual observers.

Neither Witney nor Mark has ever publicly addressed the rumors, so the exact timeline of the alleged romance—or its fallout—remains a mystery. What is clear, though, is that whatever happened, they eventually went their separate ways, each moving on to different partners both on and off the dance floor.

For the PenaVega fans, the revelation was a reminder of how much drama can simmer beneath the glitter of a televised dance competition. Whether the feud was a fleeting misunderstanding or a full‑blown fallout, it adds another layer to the already tangled history of Dancing with the Stars.

As the podcast ended, Alexa summed it up nicely: “It’s wild how much happens behind the scenes. You never really know what’s going on until someone tells you.” The conversation left us all wondering what other secrets might still be hidden behind those studio lights.
