Take a guess at what makes this soulful crooner happy -- the reason almost seems ironic.Well, Josh Groban says he is happy to be single, though he does sometimes get lonely.The 'Brave' singer says that although he enjoys being in a relationship, at the moment he is content to have no ties in his personal life, but would like to settle down at one point.He said: "I am single and I do enjoy it. I enjoy being in a relationship too, though. I like the saying, 'A good relationship is a friendship on fire.' It's nice to have a companion - especially when you're a solo artist, as it can be very lonely."However, Josh is not short of offers and regularly has women propositioning him, especially female fans who he meets backstage.He added to Britain's HELLO! magazine: "I do a rather extensive meet and greet backstage sometimes and there can be 100 people and the person you least expect, who looks like they're dressed to go to church, is squeezing your butt while they take a picture. The behaviour of some fans never ceases to amaze me."
