Noirín and Marcus face eviction vote

Irish femme fatale Noirín will go head-to-head with Marcus in tonight’s 'Big Brother' eviction vote.

If the Irish beauty gets the boot, her time with ex-boyfriend Isaac Stout, who joined the show on Wednesday, will be short.

From the moment he entered the house, the 23-year-old entertainer and bar owner from Ohio in the United States embarked on a mission to rekindle their relationship, later telling her “Daddy’s back”.

Noirin, 25, who has been sharing kisses with fellow contestant Siavash, fell back into Isaac’s arms and told him: “I’m really sorry I made a mistake.”

However, while the American’s arrival has left Siavash out in the cold, it may have helped to heal his rift with hirsute window fitter Marcus, who has an unrequited affection for Noirín.

Noirín and Isaac met two years ago while she was travelling in Australia and he appeared on the reality show 'The Real World: Sydney'.
