Chris Martin is known for his unique collaborations with hip-hop artists like Jay-Z and Kanye West, but it now seems that the rocker has set his sights on a new genre -- country. While his wife, Gwyneth Paltrow, was busy filming 'Country Strong' in Nashville with Tim McGraw, McGraw's better half, Faith Hill, took full advantage of having the Coldplay frontman in her neck of the woods.

"My wife is a huge Coldplay fan, and they spent a lot of time writin' songs," McGraw told Chelsea Handler last night during a sit-down on her E! chatfest.
