No, but Eileen is 20 years older than Kieran. The point Sarah was making was that Eileen is using the age card herself in the house to start fights. I think shes right, Eileen is very worried by her age, you can tell by the shortness of her temper even when housemates are talking about other people they know who are older.
Eileen's nomination of Kieran was also suspect too, in the fact that as we saw the convo they had was about older people he knew who needed less sleep. Eileen turned it round and had a go at him for saying she needed more sleep, and then nominated him for talking about older people. Crazy, Eileen is a fake, I'm sorry but thats how I see it. Everything she does in the diary is calculated, and the little digs she makes to get people to pop are silly and childish for a grown woman of any age.
