OK! Exclusive: Pharrell Dishes On Britney

It turns out that even Britney Spears' collaborators catch up with her through the news.

Producer extraordinaire Pharrell Williams, who wrote Blackout's most ballad-y number, "Why Should I Be Sad," recently revealed to OK! that writing a song about the poptastrophe's life was easy-breezy — he just read about her in the papers.

"I basically just read clippings," admits Williams. "I thought it'd be funny to take everything people were saying about her and turn it into a song."

"Why Should I Be Sad" is a sardonic take on the dissolution of Brit-Brit's marriage to Kevin "K-Fed" Federline — and mentions her supporting his Vegas habit and his alleged dalliances with other women.
