The 51-year-old star has been open about her problems with spouse Ray Fensome - the father of her 16-year-old daughter Ciara - and Linda Nolan thinks her time in isolation on the show will give her space to reflect on their union and figure out what she wants to happen when she leaves the famous house.

Linda told new! magazine: "Absence makes the heart grow fonder, but doing 'CBB' could be a make or break situation.

"Coleen loves him and when they're together they're really funny and have a laugh.

"They have a beautiful daughter and their lifestyle is great, so I hope they can work things out.

"There's a lot of time to think [in the house]. She has said she isn't blaming it all on Ray and that she has things to work on herself, so she will; be reflecting on it.

"But she's a fighter. She loves Ray and wants her marriage to work.

"But maybe she'll think, 'Actually, I'm alright on my own. I'm in here on my own and I'm OK.' Or she might decide, 'As soon as I'm out of here I want to fight for it, because I want to be with him.' "

Regardless of what the pair decide to do, Linda just wishes her sister and Ray were better at communicating with one another.

She said: "If they're arguing, Coleen walks away because she doesn't like confrontation and it's the same with Ray.

"He'll go into a mood and won't speak to her for four days.

"It'as a way of avoiding the situation. I'd say to them talk about the situation, and if you can't resolve it, then get out."
