Rousey’s 17-year-old sister, Julia De Mars, plays a young Rousey in the clip, beating up boys at school and standing on a podium accepting a medal.
In a Facebook post, Rousey shared the promo video, clearly excited for her sister’s starring role.
De Mars is 11 years younger than the 28-year-old Rousey, who is skyrocketing in popularity as the face of UFC. Rousey will fight Holly Holm at the bout on Nov. 14.
