The `Wild Horses` singer is expected to perform for Pope Benedict XVI - who is making his first visit to Britain in September - as part of a public mass in Glasgow, Scotland.
A spokesman for the Catholic Church in the country said: "Negotiations are still under way but we expect SusanBoyle to perform as part of the Papal Mass at Bellahouston Park."
The 49-year-old star - who is from Blackburn, West Lothian, in Scotland - recently spoke of her desire to perform for the head of the Catholic Church when he comes to the UK.
She said: "The Pope is a very special person and singing for him within the mass, it`s not just for him, it`s for everybody."
Around 100,000 worshippers are expected to attend the service.
A statement from Scotland`s Catholic bishops said: "The Catholic Church welcomes the confirmation by Glasgow City Council that Bellahouston Park will be available and suitable for the visit of Pope Benedict XVI.
"The park provides a wonderful venue for what will be a tremendous event. It is a place that has a great resonance for Scottish Catholics, many of whom remember the wonderful day in 1982 when Pope John Paul II said mass there."
