Cheryl Cole has reportedly gotten domesticated for her friend Will.i.am.

The singer has been rustling up some culinary delights for the Black Eyed Peas musician while he is in the UK to film The Voice.

A source told Britain's The Sun newspaper that Cheryl is saving the I Gotta Feeling hitmaker a fortune on room service.

"Will.i.am loves the food," the insider revealed. "It makes a change from backstage catering, restaurants and hotels."

"Cheryl has always been interested in food but recently started taking it seriously. It's a way to unwind."

Cheryl apparently loves cooking curries and has already made a Sunday roast, cakes, scones and tarts for Will.

The British singer is reportedly set to write a tell-all autobiography after her former mentor Simon Cowell reportedly said that he would have "liked an affair" with her in his new unauthorised tome, according to The Mirror.

Cheryl's memoir will allegedly include tales about how Simon told her to dump ex-husband Ashley Cole and how she felt "stitched up" after she was humiliatingly axed from X Factor USA last year.
