The singer added, "Her favourite brand costs around 1,000-pound a bottle so not everyone can get their hands on it that easily! The X Factor champ will feel they're on the A-list already."
The 39-year-old crooner dished out a cool 50,000pounds on the Angel bubbly at a party for pals in London last week. The champagne comes in hand-finished silver bottles and that makes up part of the price. The source said: "She wants the winner to feel extra special and this champagne is certainly one way of making sure that comes true."
