George Michael's funeral will take place in a tiny chapel that seats just 30 people

A source told The Sun on Sunday newspaper: "The funeral is going to be a very small, private gathering. The chapel only seats 30 so, apart from family, there won't be many others there.

"The details are a closely-guarded secret. Most guests will be told what's going on a few hours beforehand. The idea is to avoid them being mobbed by fans trying to get a glimpse of their idol's farewell."

Though details for the service are being kept as quiet as possible, it is believed former Spice Girls singer Geri Horner will give a reading after George's Wham! bandmate Andrew Ridgeley - who gave a touching tribute to his friend alongside backing singers Pepsi & Shirley at the BRIT Awards last month - felt unable to address the congregation as it would be too emotional.

The source added: "Andrew overcame massive anxieties to perform a tribute at the Brits. He was asked to read at the funeral but felt it would be too much. Instead, Geri has been asked to speak.

"The choice has raised eyebrows among some of his friends as the two weren't close when he died."

It was recently claimed George has left his £10 million London mansion to his older sister Melanie, 55.

Melanie is thought to have already moved into the home whilst she plans the funeral of the ex-Wham! star.

A source said: "George was very close to his whole family but he had a particularly special bond with Melanie, who was by his side at the height of his fame.

"She adores the Highgate house, one of the first he bought. They shared some wonderful times there and it has a special place in her heart. Melanie is staying there at the moment while she organises the funeral."
