The 'Rolling in the Deep' hitmaker will team up with the celebrity TV chef next year after her 13-month-old son Angelo's ''godfairies'' gave her the baking master class as a Christmas present.
A source told the Daily Star newspaper: ''Adele has a group of close male friends who she calls 'Angelo's Godfairies', because she isn't religious and doesn't believe in traditional godparents.
''One of her close circle thought to give her the Nigella present this Christmas because she's become so keen on cooking.''
The 25-year-old singer has become such a fan of Nigella's that she has been religiously following her Christmas turkey in brine recipe, as well as cooking up delicious edible decorations.
The source explained: ''Adele loves cooking traditional English meals and nobody does that better than Nigella.
''Adele admires her and is keen to learn more, so it was the perfect present for her.''
Meanwhile, Nigella has had a tough time over the last year, including splitting from her husband Charles Saatchi, hitting the headlines for her alleged drug abuse, and being caught up in a legal battle with her former nannies Francesca and Elisabetta Grillo, who were cleared of defrauding the former couple.
This Doctor won't be saying 'goodbye' in the same way as those who have left the series in recent years.
