Kailyn Lowry says she didn't get "beat up" while filming the "Teen Mom 2" reunion. The 26-year-old spoke out Saturday on Twitter following a reported altercation with co-star Briana DeJesus. "I didn't get beat up. I didn't get hit. Reeeeeeeelax," she told her 1.4 million followers. Us Weekly reported Saturday that Lowry and DeJesus got in a physical fight at the reunion. Lowry told E! News on Sunday that her conflict was actually with DeJesus' sister, Brittany DeJesus. "Brittany ran up behind me and pulled my hair. That was it. Briana didn't do anything," the star said. "I confronted [Briana] alone and she wouldn't get up," she added. "I just wanted to hash it out. But she didn't want to." DeJesus dated Lowry's ex-husband, Javi Marroquin, last year. Lowry, who shares 4-year-old son Lincoln with Marroquin, wished Marroquin her best following his split from DeJesus in January. "It's none of my business, so my mouth is closed. I wish Javi the best, as always," she told Us Weekly. "Teen Mom 2" is in its ninth season on MTV. The series stars Lowry, DeJesus, Jenelle Evans, Chelsea Houska and Leah Messer.
