Coldplay frontman Chris Martin may not seem the type to have mad hip-hop cred but then again, we never thought that Kevin Federline would have a higher appeal than his ex-wife-in-the-making, Britney Spears. But Mr. Paltrow is racking up just that, having guested on Jay-Z's 2006 comback album, 'Kingdom Come,' and with an upcoming appearance on Kanye West's latest effort, 'Graduation.'
Martin and West team up on the album's first single, 'Homecoming,' while 'Late Registration' collaborator Jon Brion (Fiona Apple) will make his return. "Jon wasn't just a producer," West told Billboard. "He was such a good friend and a great person to bounce ideas off of in the studio. It was the whole experience."
'Graduation' is tentatively due late this year.
