MTV has confirmed it has suspended filming Crazy In Love with Kerry Katona while the mum-to-be is treated for depression in The Priory.
Kerry Katona married cab driver Mark Croft last year
Kerry's publicist Max Clifford told Newsbeat she has been readmitted to the clinic, but it is part of her regular treatment for bi-polar disorder.
He denied that her readmission was connected to reports that husband Mark had cheated on her.
He said: "Everything is good in terms of her marriage and career-wise."
Mr Clifford denied reports that she was having a nervous breakdown.
He added: "She suffers from bi-polar disorder. Some days she is down. There is nothing different at the moment."
People with bi-polar disorder, or manic depression, suffer from dramatic mood swings.

He denied that her treatment was anything to do with drug abuse saying that she had recently undergone tests that proved she was clean of illegal drugs.
The 27-year-old's fourth child is due at that beginning of May.
An MTV spokesperson said that Kerry was one of the channel's "most popular celebrities".
Filming of the reality show Crazy In Love has stopped this week while she receives treatment but the channel is still "looking forward to filming up to the birth of her child".
