Noirin Kelly's ex boyfriend Isaac Stout, will be going into the house tonight.

Isaac is 23 years old, an entertainer/bar owner, from Ohio, USA.

This will come as a big shock to both Noirin and fellow nominee Marcus Akin, who had a massive crush on the Irish temptress.

It will also ruffle the feathers of Siavash Sabbaghpour, who has a romantic interest in Noirin.

Interesting to see how it will affect this weeks eviction.

Will Isaac's arrival help Noirin stay in the house? Time will tell.
