Martin Bashir is "seriously unwell" with coronavirus-related complications.
The 57-year-old journalist - who is best known for his 'Panorama' interview with Princess Diana in 1995, and he competed on 'The X Factor: Celebrity' last year - is battling Covid-19-related complications, and the BBC, where he works as the BBC News religion editor, have wished him "a full recovery".
A BBC spokeswoman said: "We are sorry to say that Martin is seriously unwell with Covid-19-related complications.
"Everyone at the BBC is wishing him a full recovery. We’d ask that his privacy, and that of his family, is respected at this time."
Martin was recently nominated for Best Performance at the National Reality TV Awards for his efforts on 'The X Factor: Celebrity' in 2019.
The star captured the nation's heart with his performances on the show, but he was later eliminated in week three.
But before he was voted off the show, Martin claimed some of his BBC colleagues had called him "an idiot" and "an embarrassment" for taking part in the programme.
He said: "It has been humiliating. Some of my colleagues at the BBC have sneered a bit and said, 'Oh, you look like an idiot. What an embarrassment.'
"But I feel I've tried something new. I do feel I've made some progress.
"Not a lot, but some progress."
Diana's infamous interview with Martin features in a new Channel 4 documentary, 'Diana: The Truth Behind the Interview'.
During the chat, Diana - who died in a car crash in Paris in 1997 - famously declared her marriage to Prince Charles felt "crowded" because "there were three of us" involved, referring to the heir-to-the-throne's now-wife Camilla, Duchess of Cornwall.
