Noirin's ex to enter house today

Noirin's ex-boyfriend will enter the Big Brother house today, it has been revealed.

American Isaac has agreed to take part in the programme in a bid to win back the heart of his former girlfriend.

The pair met on Australian reality show The Real World: Sydney, while Noirin has mentioned her ex on a number of occasions to fellow housemates.

Meanwhile, Isaac has admitted that he still has feelings for the Dubliner and has not found love since their relationship ended.

However, Noirin's mum Jacinta recently claimed that her daughter would quit the house if Isaac turned up.

If she does not leave by choice, the 25-year-old may be forced to go on Friday as she is up against Marcus in this week's public vote.
