Kanye West didn't write 'Famous' lyrics about Taylor Swift?

Kanye West and Taylor Swift locked horns over the rapper's controversial lyrics about the pop star in his latest track "Famous", but it's being claimed now that he did not even write the infamous lines.
R&B star Rihanna's ex-PR Jonathan Hay has alleged the lines were written by hip-hop artist Cyhi The Prynce, real name Cydel Young, who is actually credited on the track, reported Daily Mirror.
"The lyrics are written by Cydel. Kanye got all the backlash but he isn't even the one who wrote them. Cydel lays down the lines and Kanye will OK them and perform them," Jonathan said.
