Adele feels ''too young'' to write an autobiography.

The 24-year-old singer, who was recently named the UK's richest young musician at £30 million, reportedly turned down a seven figure sum offered by Harper Collins to pen her own story as she wants to keep her life stories private from the public eye.

Adele - who gave birth to son Angelo last Septemberwith fiancé Simon Konecki - also feels she needs more ''life experience'' in order to conjure up a book.

A source revealed to The Mirror newspaper: ''Adele's never been a really showy person, so it was always going to take a lot to get her to write her life story anyway.

''But even though she received a lucrative offer, her primary concern was that she doesn't want to write a book about just 24 years. She feels she'd rather wait until she has more life experience to write about.

''She'd never say never, but she did say 'not now'.''

The couple recently splashed out on several pieces of art work by infamous artist Andy Warhol for their home in Sussex, Southern England, and plan to add more to their collection.

A n insider said: ''Adele and her partner Simon Konecki had the pair of prints delivered to their house in the past month.

''They're Warhol fans and the butterfly works are a good investment as well.

''The Warhols have already been hung in pride of place on the walls of the living room at the huge house.

''The couple are hoping to get more contemporary art for the walls to add to their collection, including paintings by Damien Hirst and Banksy.''
