Patty Griffin

Album marks her first new music in four years and includes backing vocals by Led Zeppelin singer on two tracks.

Singer discusses his past and future - and veers away from doing Led Zeppelin a “disservice” with another reunion.

She's stayed mum for over a year as fans have speculated and rumors have swirled, but now that she's making the publicity rounds for her new album, Patty Griffin's coming clean about whether or not she and Robert Plant are really married.

Robert Plant joins singing -- but definitely, definitely not married -- partner Patty Griffin for three songs on her forthcoming solo album 'American Kid,' continuing a collaboration that began with 2010's well-received 'Band of Joy.'
