Bruno Mars picky with collaborations

Singer Bruno Mars has said he is picky about who he collaborates with.
The 31-year-old "Locked Out Of Heaven" hitmaker would turn down a "sweet cheque" if he doesn't feel right about the collaboration, reported Contactmusic.
"I just don't want to feel gross. It's as simple as that. I don't want to feel gross, I don't want to regret any decisions. Even if I turn down a sweet cheque because I don't want to be on that billboard, hawking some ... To the world - I just don't need to do that. Because you get one shot at this," Mars said.

"I'm not a model. I'm not an ice skater. I'm not a chef. I'm here to do music. And I want to be able to look back and say, 'Yeah, I did it the way I wanted to do it.' Whether it triumphs or fails, I can live with that.
