Carol's revelation comes not long after she was saddened by the death of one of her friends. Last week, she posted a moving remembrance of Squadron Leader George Johnson.

Among the snaps were several photos of Carol and George posing together. Alongside the candid snapshots, the 61-year-old gushed: "My friend Squadron Leader George 'Johnny' Johnson died peacefully last night.
"Age 101 he was one of the most incredible human beings I have ever had the privilege of meeting. We first met on the Clifton Suspension Bridge and the last photo here is of the bridge this morning bathed in sunshine as if a reminder of the spirit of this fine man."
