Strictly Come Dancing judge Motsi Mabuse will miss the BBC show this weekend after coming into close contact with someone with Covid.
She confirmed she was contacted by the NHS test and trace app over contact with a Covid case on November 21.
She will be replaced by Cynthia Erivo, who filled in for judge Craig Revel Horwood last weekend after he tested positive for Covid-19.
In a statement, posted on social media, the 40 year old said she was "gutted" to be absent from this weekend's shows.
She wrote on Twitter: "I am gutted to say I will have to miss this weekend on Strictly. Yesterday, I was contacted by NHS Test and Trace as being in close contact with someone on Sunday 21st Nov who has since tested positive."
She added: "Being double vaccinated and booster as I am, would normally mean exemption from isolation under the close contact rules, but unfortunately German EU vaccines are not recognised and neither is my booster in this instance - so I must follow UK Government guidance and can only return after November 30.
"Our health is the most important thing and luckily I have been tested multiple times this week and I am negative."
"I am healthy. I am with my family - that's what matters."
She concluded: "I wish everyone good luck. Sending my love. Keep dancing. Until then, lots of love and stay safe."
Only six couples remain as Strictly Come Dancing enters its final few weeks.
The hit BBC show is about to enter week 10 with new dances and songs announced for the weekend.
During week nine Tom Fletcher and Amy Dowden's time in the competition came to an end in the Musicals special.
