A MYSTERY X Factor star will be performing in Cheltenham on Christmas Eve.
The reality TV star will be taking to the stage of Christ Church in Malvern Road on Monday.
The church is keeping tightlipped over who will be performing as part of its Christingle celebrations.
But the clergy said the celebrity had approached them and volunteered to do the gig.
The Reverend Tim Mayfield said: "I am sure it will be a great day. The Christingle services are always very popular and I am sure this year will be no exception."
The services take place at 3.30pm and 5.30pm and are expected to have audiences of 550 for each performance.
The events will raise funds for the Children's Society and is one of the church's biggest charity fundraisers.
