Coronation Street's Sue Cleaver tells birth mother story on I'm A Celeb

When she was in drama school, she recalled that the Royal Exchange in Manchester was looking for “tiny parts” for the theatre production of Oedipus.

After walking into an audition, Sue shared that an actor said to her:“Oh my god, she’s the absolute double of my wife when I met her.

The actor then asked Cleaver for her date of birth.

He then asked the young actor where she born and she replied 'Barnet', before he rung his wife and said ‘I’ve found her’.

At hearing the story, property expert Scarlette Douglas gasped, saying: “What!”

Former England footballer Jill Scott chimed in: “Nah, that has just given me goosebumps. That is the most incredible story I think I’ve ever heard.”

Meanwhile, Comedian Babatunde Aleshe added: “That’s spooky. That’s mad.”

Cleaver went on to say: “It’s uncanny and I’ve got two half sisters who are all in the business.

“It’s lovely because my mum and my birth mother, we’ve all met, been out for dinner, we’ve all kept in touch, so we’ve all had a lovely relationship ever since, so it’s a nice ending. I’m very lucky.”

She also noted that she is normally a really private person but she felt safe and supported in the camp.

"It felt good to share," she added.
