CHICAGO, Oct 4: Ask Macy Gray about her net worth, and the Grammy-winning R&B singer and songwriter is not sure – though she is perfectly willing to help out with a little online research. She stops the interview to trawl celebritynetworth.Com, where she plugs her name into a search engine and pulls up a number. A very large number. “Wow!” exclaims Gray, 45, an Ohio native who calls Los Angeles home. “It says here I’m worth $38 million. But I don’t know where they got that figure from, because I don’t even know how to figure that out. But if it’s right, I’d go cash that in right now and go shopping.” (agencies)
