Amanda Holden rushed to her sister’s hospital bedside after she was involved in a horror car crash on Thursday morning.The Britain’s Got Talent judge, 45, went straight to see Debbie Holden, 44, after learning of the accident. Debbie is said to be in a critical but stable condition in the intensive care unit of a Cornwall hospital and is expected to make a full recovery.

“Amanda is in absolute agony. She’s very close to her sister,” a source said. “She immediately travelled to Cornwall to be with Debbie.” They added to The Sun: “It’s been a very difficult 48 hours and the whole family have been pulling together and trying to keep positive.”

Britain’s Got Talent judge Amanda 45, had been a guest at Simon Cowell ’s boozy 57th birthday bash in London on Wednesday night. The sisters became close in adulthood after a fractured relationship with their father Frank as kids.

Their dad split from mum Judith in 1976 after six years of marriage on grounds of unreasonable behaviour due to his heavy drinking. The pair became particularly close in 2012 when Amanda almost died through childbirth complications.
