'CSI: Miami' Star Eva LaRue -- Husband Says Adios ... Files for Divorce

It's case closed in the marriage of "CSI: Miami" star Eva LaRue -- her husband just filed for divorce.

Joseph Cappuccio filed divorce docs -- obtained by TMZ -- citing irreconcilable differences. The couple was married on June 28, 2010 and have no children.

And ... holy crab! Joseph -- a seafood businessman -- is asking the court to reject any request LaRue makes for spousal support.

The writing's been on the wall for years ... LaRue and Cappuccio were engaged TWICE before finally tying the knot.

Oh yeah, and it probably wasn't a good idea to post your wedding video online.
