Gwyneth Paltrow has opened up about her marriage with Coldplay frontman Chris Martin.

The couple, who tied the knot in 2003, have always kept their marriage under wraps from the UK's press.

"Marriage is hard. Chris and I have had our ups and downs, big time. Marriage is way more complicated than just who gets to control the remote," Paltrow told The Sun.

She added: "But hopefully we keep heading in the same direction and getting through the obstacles."

Meanwhile, Cee Lo Green has confirmed that he and Gwyneth Paltrow have recorded a new version of his hit, 'F*ck You'.
