Vanilla Ice's marriage is officially ice, ice baby -- his wife just filed for divorce after nearly 20 years together ... TMZ has learned.
Laura Van Winkle filed the docs Tuesday in Florida. They have 16 and 18-year-old daughters. Sources close to Ice tell us he and Laura have actually been separated for a few years now, and she's just making the split official.
The couple toughed it out after he was twice arrested for domestic battery ... in 2008 and 2001.
Unclear if Ice was blindsided by Laura's filing, but he seemed pretty chipper a few weeks ago when we got a Delta employee serenading him.
