Motsi announced on Thursday night that she’ll be appearing on the show via video-link this weekend, as she needed to make an urgent trip to Germany earlier in the week.
She explained: “Earlier this week I needed to travel to Germany for an urgent reason. I will of course be following the UK government guidelines and self-isolating for 14 days.
“I’ll be watching from home and by the power of technology, should be in your living rooms.”
“Watch out though, I’ll be doing my own hair and make-up,” she joked.
Motsi’s announcement came hours after Strictly bosses confirmed that Nicola Adams had been forced to leave the competition, after her partner Katya Jones tested positive for Covid-19.
A spokesperson said: “Katya is asymptomatic and the pair are now self-isolating separately following the latest government guidelines.
“As part of the protocols outlined ahead of the series, this sadly means they will no longer be able to take part in the competition.”
Regular Strictly judge Bruno Tonioli is also missing from the series this year due to travel restrictions, as he’s currently also a judge on the US version of the show.
However, he is offering weekly critiques in the Sunday night results show, recorded from his home in LA.
