Since entering the Love Island villa, she's shocked her co-stars by claiming not to know what Brexit is, or even an earlobe for that matter.

But according to one of her school friends, she's actually a secret brain box who scored three B's at A Level and studied Childhood and Youth Studies at Liverpool Hope University before dropping out to be an actress.

"She's definitely not that stupid. I can't believe no one else has said anything," said the friend, who claims she scored A Levels in ICT, Science and Health and Social Care at John Bosco Arts College in Liverpool.

"She did really well in her A Levels and GCSEs. She managed to get the grades to do that course, but she dropped out to pursue an acting career," the insider continued.
