Robin Thicke and his wife ''make love as much as possible''.

The 'Blurred Lines' singer has been married to his high school sweetheart, Paula Patton, since 2005 and says they keep their romance alive by making sure they always have time alone.

He told People magazine: ''When we feel like we're in a bad place, we try to switch it up. We'll go for a walk or put on some fun music. You just gotta laugh, dance and make love as much as possible.''

While Robin has been criticised for the explicit video accompanying 'Blurred Lines' - featuring topless models - he claims Paula was fully behind it and even convinced him to release it.

He explained: ''It was director Diane Martel's idea. When I saw both versions I said, 'Maybe just go with the clothed one' but my wife saw the topless one and was like, 'No way! That is so hot, sexy and original.''

Robin, 36 and Paula, 37, have three-year-old son Julian together and the singer says his young one is already showing signs of following in his footsteps.

He said: ''He's written six songs already. He's three and wants to be a rock star! He's my little road dog and the best thing to ever happen to me.''
