Julianne Hough’s teenage niece, Star, claims in a viral TikTok video that her aunt had a sexual encounter with actor Leonardo DiCaprio.

Star, the daughter of Julianne’s older sister, Sharee Hough Selman, said that her aunt told her that DiCaprio was “not good in bed.”

She asserted that her claim was not a lie and invited nonbelievers to “look it up.”
