David Alan Grier -- In Living ... Single

We've just learned David Alan Grier's wife has filed for divorce.

According to the docs, filed today in L.A. County Superior Court, Christine Kim cited irreconcilable differences. The two were married in July of '07 -- they have a 1-year-old daughter together.

If you remember back to December of '07, we got David busting out of a club while Christine was at home, 7 months pregnant. Not that his divorce has anything to do with that ... we're just saying.
