The second Strictly Come Dancing judge in as many weeks has been made to isolate following close contact with a Covid case.
The BBC dancing show's Motsi Mabuse shared with fans on social media that she was unable to enter the UK, despite having two vaccine doses and a booster, as the UK government does not recognise German vaccines.
She will be replaced by Cynthia Erivo, the Oscar-nominated singer-songwriter who filled in for judge Craig Revel Horwood after he was forced to pull out over contact with a Covid case.

Erivo's first big break was in the Channel 4 hit series Chewing Gum as Magdalena, but has since played roles in a number of award-winning films.
In her social media post, Motsi Mabuse stayed positive, saying: "Our health is the most important thing and luckily I have been tested multiple times this week and am negative.
"I am healthy, I am with my family [and] that's what matters.
"I wish everyone good luck, sending you my love, keep dancing."
This news comes in the same week as Motsi's sister Oti, a professional dancer on the BBC show, announced on social media that she would be unable to return to South Africa over Christmas due to fears of a new Covid variant.
A spokesperson for Strictly Come Dancing said: "We can confirm Motsi Mabuse will not be taking part in Strictly Come Dancing this weekend.
"We are delighted that Cynthia Erivo will be joining us as a guest judge again, joining Craig Revel Horwood, Anton Du Beke and head judge Shirley Ballas on the judging panel.
"We look forward to having Motsi back with us next weekend."
