Miranda Hart will not be returning to Call The Midwife despite suggestions from producers that she would.
The actress had been due to reappear in the BBC period drama as loveable midwife Camilla "Chummy" Browne.
However, she tweeted on Thursday:
The 43-year-old quit the show during series four due to work commitments, with Chummy being sent to a mother and baby unit to explain her absence.
Miranda went on to star in action movie Spy alongside Jason Statham, Melissa McCarthy and Jude Law.
But the show's producers later said that she was returning to the show for series six.
Dame Harriet is set to play Sister Ursula when the series returns next year.
