Strictly Come Dancing professional Nadiya Bychkova is reportedly isolating after testing positive for coronavirus.
Along with all of her fellow dancers, the 31-year-old is undergoing regular COVID testing as the show gears up to return next month.
According to The Sun, her most recent test came back positive and as a result she - and several of the crew who came into contact with her - must now self-isolate.
"This isn't exactly the dream start. Obviously BBC bosses are panicking," a source told the newspaper.
"They are taking every caution to be COVID-secure, and keep everyone safe, but can't control everything. Nadiya tested positive during one of the first meet-ups, during the studio rig.
"Thankfully none of the celebs have started training yet, but it still means anyone who came into contact with her has been told they must isolate.
"Obviously the fear is that dancers and celebs will continue to test positive as the rehearsals and training starts for real later this month.
"Yet more measures and precautions may need to be put in place - clearly execs won't take any chances, and safety is their number on priority."
The BBC is in the process of revealing the celebrities in this year's lineup, with confirmed names so far including Greg Wise, Sara Davies, Dan Walker and Katie McGlynn.
