LOL! A 99-year-old granny was accidentally told she's pregnant!

Los Angeles - A 99-year-old woman was mistakenly sent a letter informing her she was pregnant.

Doris Ayling - who already has three children, all of whom are pensioners themselves - received a letter from Portsmouth Hospitals NHS Trust telling her that she was set to welcome another child.

She told The Sun newspaper: "I'm almost 100, so how can I be expecting?

"I have three children and 20 grandchildren - but I haven't been pregnant for 70 years."

Her son Brian, 76, was also amused by the administrative error.

He said: "It's very amusing. She's got enjoyment out of it and everyone had a good laugh. It's just one of those things."
