"Kendall is a competitive dancer who works full-time as a children’s dance instructor at Rockstar Academy of Dance in Nashville," Starcasm reported on Monday. "She has a twin sister named Jarren who is an assistant director at the same dance studio."

Withrow is also said to be a friend of Mackenzie Douthit, star of Teen Mom 3. Months ago, Douthit shared a photo of Withrow and her twin sister, along with a photo of herself. In the caption, she told fans, "Cutest twins ever;) but uhh I’m pretty sure I’m their triplet."
