The professional dancer, 31, confirmed ‘an announcement will be made later’ ahead of her Dancing On Ice judging debut this Sunday.
Oti, who joined Strictly in 2015 when she was partnered with Olympic boxer Anthony Ogogo, 33, revealed BBC bosses ‘congratulated’ her after she landed the ITV job.
She told MailOnline: ‘There will be an announcement that will be made later.
‘But for me as a person in entertainment, I really want to learn and grow and I want a long career, especially in this country.
‘I moved all the way from Africa so I must make something of myself so I am really trying to learn and do as much as I can for as long as I can, while I can.
‘I have done a couple of panel shows but I have been a dance captain and a dance detective, but I have never been said to be a judge.
‘I love competition and I love watching people learn new skills and try to get better every single week.
‘It is a journey that I absolutely enjoy, to be a part of, and watch. To know that I am doing it now with ice-skating is very exciting for me. I can’t wait, I am buzzing.’
Strictly judge Motsi, 40, has been guiding younger sister Oti’s career and giving her tips on how to become a top TV judge.
Oti, who won the Glitterball trophy for two consecutive years with Emmerdale star Kelvin Fletcher, 37, and comedian Bill Bailey, 56, said: ‘We are really close my sister and I and we know that we are quite loud and bubbly and her advice to me was just to be myself.
‘Everyone from the BBC who congratulated me said the same thing. They said be yourself, be honest, say what you see and say what you feel and say how you hope they would improve and better themselves.
‘At the end of the day it’s about the celebrities and the show and helping them get better to actually win.’
Oti made her judging debut in 2019 alongside Cheryl Tweedy, 38, in BBC One series The Greatest Dancer but her switch to ITV show The Masked Dancer impressed bosses, eventually leading to her role of judge on Dancing On Ice.
The South African dancer was also recently revealed as the host of new ITV show Romeo & Duet, telling her Instagram followers this week: ‘My heart is just full with excitement and joy about this announcement.’
