If a celebrity is defined as one who is celebrated, then perhaps DBOBE qualifies, given he's thought of rather highly around these parts.
I think though, that modern celebrity is often taken to imply that a persons fame has taken on a life of its own, and broken loose from whatever talent (or lack thereof) caused their fame to begin with. In this sense, David does not qualify, and I hope he never will.
As for God... Who knows? What better way to get close to God that by being among the stars, though?
Have a great weekend
