Ananova:

The roles for this week's wedding task have been finalised.

Michelle had wanted to be the bride and yearned for Stuart to marry her, but he refused.

The roles are now being taken by Shell and Victor.

The wedding takes place on Wednesday, says the official Big Brother website.

Stuart is now the father of the bride and will give Shell away. He's also responsible for decorating one tier of the wedding cake.

Nadia's the bridesmaid and has to make the bridesmaid's dress, prepare the bride's hair and make-up on the wedding day, and walk behind the bride in the wedding procession.

The best man will be Dan. He too must decorate one tier of the wedding cake, look after the wedding rings on the day of the wedding, and write and deliver the best man's speech.

The wedding ceremony will be conducted by Jason, while Michelle will be providing the music on the big day. She has to learn and sing the hymn 'Pie Jesu' for the wedding service.
