Mabuse told the Radio Times: “I’ve never really spoken about it because I’ve tried for so long to think about it this way: I work on a show that 10 million people love; if 10 or 100 people aren’t nice to me, that is not representative of everyone else’s views.
“To get tweeted or receive a message in my inbox being racially abusive, or fat-shaming me, is horrible. But it’s written by a person who can’t even face themselves in the mirror.
“The hard stuff that I’ve been through, with the racism and discrimination, is proof that people still have a lot to learn. The more hate I receive the more of a reason it is to carry on doing my job. I have to show young girls that anything is possible. I have to fight, and be strong.”
The 31-year-old South African dancer - who won Strictly in 2020 with comedian Bill Bailey and in 2019 with Emmerdale star Kelvin Fletcher- also spoke about her struggle to rise up in the entertainment industry as a Black woman.
She said: “When you do something good, it’s not good enough because you’re Black. Some people say you’re on a show because the channel needs to tick a box.
"Which means you’re not worthy of being there. But I think that just shows where people who make those comments are in their own lives. Being Black makes me special.”
She has previously served as a TV judge on BBC's The Greatest Dancer.
Oti previously revealed how it was her sister Motsi who set her up with her now-husband and dance partner Maurius Lapure.
She said: “When I said I wanted to become a professional dancer, Motsi suggested a few boys I could trial with as dance partners. Marius was the first and only try-out I had. I cancelled all the others. I was like, ‘This is the one.’”
