Brand new Big Brother housemate Noirin is no stranger to reality TV, in fact less than two years ago she appeared on MTV’s ‘Real World Sydney.’

On the series Noirin hooked up with cast member Issac and shared a brief relationship with him, until the show ended and the distance caused problems between them.

Noirin is obviously a bit of a fame seeker and this revelation has put me off her immensely……not that I liked her that much to start with! Have any of you spotted any other housemates before?
