Robin Thicke says his wife is an ''inspiration''.

The 'Blurred Lines' hitmaker - who was photographed with his hand on another woman's butt before it was claimed they shared a passionate kiss - has praised Paula Patton for being his ''muse''.

He claimed he wouldn't ''be alive'' if it wasn't for his wife, who recently said there was no truth to the allegations.

He told Prestige magazine: ''I don't know if I would still be alive in some ways if it wasn't for Paula.

''She's been my rock, my muse, my inspiration and I love her. The whole way.''

The couple - who have been married to since 2005 and have a three-year-old son, Julian - are ''best friends'', and Paula insisted they always find time to relax as a family.

She said: ''We're best friends. We laugh a lot. But that's our down time. We do the things you're supposed to do, like work out. We love to travel together and travel with our child.

''We don't have normal jobs. So it's always a work house. Robin makes music at home and my job when I'm not on set always brings people into our home.'
