Jessie J has said that she was called 'alien' by the bullies at her school.
The singer got the name due to the medication she was given to control her irregular heartbeat which ended up turning her skin green.
She told The Sun: 'It might be kinda funny now but it was horrific at the time.
'Kids at school nicknamed me 'alien' and they threw rocks at me.'
Jessie added that her song 'Who's Laughing Now' was inspired by these experiences.
