Robin Thicke isn't sure he'd be alive today had it not been for his wife Paula Patton.

The 'Blurred Lines' hitmaker has been married to the '2 Guns' actress for eight years and credits his spouse for being his ''rock'' throughout their relationship.

He gushed: ''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.''

Paula, 37, is just as smitten with her singer husband, revealing that they get each other through tough times.

She said: ''I've been there for his down moments and he's been there for mine. Life is full of peaks and valleys. Robin has always been a great person to remind me to celebrate now. Even when it looks like I've got a role but don't know for sure, he's like, 'Let's celebrate!' ''

The celebrity couple - who have a three-year-old son, Julian, together - are ''best friends'' and when they are not working on their respective careers, they enjoy living a quieter life.

Paula added to Prestige Hong Kong Magazine: ''Talking to each other. We watch movies. Just sit and contemplate - we have a house with a bit of a view. Listening to music. Talking about what's going on in our lives.

''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 - blah, blah, blah, boring, boring. We love to travel together and travel with our child.''
