The 31-year-old former 'Strictly Come Dancing' star took to Instagram to pay tribute to her "sister" and "best friend" Tlhogi, following the 28 year old's death.

She wrote: " How is this the last time I would hold you in my arms. I am so shattered inside I can’t even begin to describe the pain. This is not how this was supposed to go. We had plans together, travel the world and dance on a beach in Jamaica for my birthday. I used to fetch you everyday from crèche, swimming, chess since we were 8. You were only 28 yet the kindest, sweetest human being in my life! I’ve lost my niece, my little sister, my best friend. Life dealt you the harshest card but you always chose to win, you always fought to come out the other side above it all with a smile on your face. I love you much with all my heart and now you’re gone and I feel lost in more ways than one to a pain I’ve never felt before. I’m still calling you and texting you trying to understand - how? Why? May you rest in peace and power my sweet Tlhogi. say hi to Koko, Abuti Neo Le Malume Tshepo. I promise to take care of Sesi, Nanikie and Mpho for you (sic)."

While Oti found fame on 'Strictly Come Dancing', she left the show earlier this year to take up a role as a judge on 'Dancing On Ice'.

She said at the time: ""Never easy to say goodbye I have been part of the most amazing TV show, Strictly Come Dancing for the past seven years and it has been an incredible time. Lifting the glitter ball twice and having the best journey with all my celebrities, but also meeting and working with the best team, crew, producers, celebs and incredible professional dancers!

"You are my family and I adore you all forever. Thank you @sarahjamesface @jack.will.g and @jasongilkison for truly believing in me."
