Will.i.am's song lyrics inspired the bestseller "Fifty Shades of Grey" and its subsequent novels, says author E.L. James.
James revealed that how she listened to his band, The Black Eyed Peas, while writing her worldwide bestsellers, reports the sun.co.uk.
"I have songs that I write sex to. One of them is the Black Eyed Peas' 'Sexy'. That is a very sexy song," said the 48-year-old.
The track, from the 2003 album "Elephunk", features lyrics like: "For you I'm a fanatic, I'm an addict, your sexy antics turn me on like automatic."
James confessed her musical tastes at the launch of her " Fifty Shades" classical album.
She added that part of the books' success was that the covers are "discreet", allowing fans to read them anywhere.
She said, "I designed the covers because in my early 30s I read a lot of romantic fiction when I was slogging in and out of London on the Tube. But they had these horrible covers with women with clothes falling off.
"I hated that and I had to bend the covers back. So I designed really discrete covers so that no one would ever know it is salacious."
