Coronation Street veteran Betty Driver has been admitted to hospital for a "private medical matter".
The 90-year-old actress - who plays Rovers Return barmaid Betty Williams - is the show's oldest star, and has been a fixture in Weatherfield since 1969.
Last year the Corrie stalwart was treated for a chest infection.
TV favourite Betty is famed for her character's hotpot.
A Coronation Street spokesman said he could not comment on her hospital visit.
A show source confirmed she had been admitted to hospital but said it was a "private medical matter".
Last year, as the soap celebrated its 50th anniversary, she insisted she could never retire from the show.
"I love working. I can't retire, I won't retire - I never ever will," she said at the time.
