Marina is originally from Ukraine, and she moved to Los Angeles a year ago. She was born in a small town in Ukraine called Konotop, which didn't have many dance or gymnastics classes, so she started learning folk dance at the age of five.
When she was in ninth grade, Marina's dance teacher urged her to join the circus academy in Kiev, Ukraine. Her family was against her dancing - they wanted her to be a lawyer instead. Her mother agreed to accept her path if she received a scholarship and passed the exams. Marina succeeded in both, passing the exams and attaining the scholarship!
In 2016, Marina auditioned for “So You Think You Can Dance Ukraine” and won third place. In 2017, she was invited to be on “France's Got Talent” and made it to the finals.
Marina recently started her modeling career with State Management, and her dream is to become someone that no one expects! 
Marina Mazepa's audition in Episode 1403 consisted of performing a ballet dance routine and then contortion. Howie Mandel, Julianne Hough, Gabrielle Union, and Simon Cowell all voted "Yes," sending Marina to the Judge Cuts.
Marina Mazepa's Judge Cuts performance in Episode 1410 consisted of performing contortion using a pole, and at one point approaching Simon Cowell at the judges' desk. Marina's performance was strong enough to advance to the Quarterfinals instead of Victor Moiseev.
Marina Mazepa's Quarterfinals performance in Episode 1413 consisted of performing a contortion routine on a scorpion-like structure before transitioning to a dance routine using nunchucks to Billie Eilish's "You Should See Me In A Crown." Simon Cowell buzzed the act, while Howie Mandel, Gabrielle Union, and Julianne Hough gave her standing ovations. Marina did not receive enough votes to advance to the Semifinals in Episode 1414, eliminating her from the competition instead of Ryan Niemiller.
